| enzyme science critical digestion: The Exocrine Pancreas Stephen Pandol, 2011 The secretions of the exocrine pancreas provide for digestion of a meal into components that are then available for processing and absorption by the intestinal epithelium. Without the exocrine pancreas, malabsorption and malnutrition result. This chapter describes the cellular participants responsible for the secretion of digestive enzymes and fluid that in combination provide a pancreatic secretion that accomplishes the digestive functions of the gland. Key cellular participants, the acinar cell and the duct cell, are responsible for digestive enzyme and fluid secretion, respectively, of the exocrine pancreas. This chapter describes the neurohumoral pathways that mediate the pancreatic response to a meal as well as details of the cellular mechanisms that are necessary for the organ responses, including protein synthesis and transport and ion transports, and the regulation of these responses by intracellular signaling systems. Examples of pancreatic diseases resulting from dysfunction in cellular mechanisms provide emphasis of the importance of the normal physiologic mechanisms. |

| enzyme science critical digestion: Enzyme Nutrition Edward Howell, 1995-01-01 Why is eating food in its natural state, unprocessed and unrefined, so vital to the maintenance of good health? What is lacking in our modern diet that makes us so susceptible to degenerative disease? What natural elements in food may play a key role in unlocking the secrets of life extension? These fascinating questions, and many more, are answered in Enzyme Nutrition. Written by one of America’s pioneering biochemists and nutrition researchers, Dr. Edward Howell, Enzyme Nutrition presents the most vital nutritional discovery since that of vitamins and minerals—food enzymes. Our digestive organs produce some enzymes internally, however food enzymes are necessary for optimal health and must come from uncooked foods such as fresh fruits and vegetables, raw sprouted grains, unpasteurized dairy products, and food enzyme supplements. Enzyme Nutrition represents more than fifty years of research and experimentation by Dr. Howell. He shows us how to conserve our enzymes and maintain internal balance. As the body regains its strength and vigor, its capacity to maintain its normal weight, fight disease, and heal itself is enhanced. |

| enzyme science critical digestion: Lipase B.K. Konwar, Kalpana Sagar, 2018-05-23 Microbial lipases are industrially important and have gained attention due to their stability, selectivity, and broad substrate specificity. Lipases are used as medicine, and they also aid in indigestion, heartburn, allergy to gluten in wheat products (celiac disease), Crohn’s disease, and cystic fibrosis. This volume considers the industrial demand for new sources of lipases with different catalytic characteristics that stimulate the isolation, growth, and development of new microbial strains. The volume narrates the challenging metagenomic approach with the isolation of the lipase gene, its cloning into Escherichia coli, culture of the recombinant bacteria, and extraction and assessment of the lipase enzyme. Lipase-producing bacteria are available in different habitats, such as industrial wastes, vegetable oil processing factories, dairy plants, and soils contaminated with oil and oil seeds, among others. This volume is the effort of the authors to document the scientific findings carried out over the last eight years in the area of un-culturable soil microorganisms. The book presents the physic-chemical features of lipases and their specific applications in different commercial industries. The in-depth study looks at metagenomics for lipases from all angles and provides a truly informative resource. It describes the biochemical characterization of lipase enzymes with the high activity in the presence of 1% tributyrin. A wide review has been presented in the book on lipase enzymes purified from a large collection of microbes present in soil, seawater, waste-dumping sites, animal systems (including human beings), and the atmosphere. Stability of enzymes over changing environments of the industry is indeed a big issue, and the book deals at length with the changing temperatures and pH and metal ion concentrations. |

As a parent of a child diagnosed with learning disabilities, she is acutely aware of the difficulties facing other parents like her, and she has devoted much of her time to helping these families. She realized that nutrition played a critical role in helping children and adults to overcome their disabilities, and has pioneered the use of probiotics in this field. Her willingness to share her knowledge has resulted in her contributing to many publications, as well as presenting at numerous seminars and conferences on the subjects of learning disabilities and digestive disorders. Her book Gut and Psychology Syndrome captures her experience and knowledge, incorporating her most recent work. She believes that the link between learning disabilities, the food and drink that we take, and the condition of our digestive system is absolute, and the results of her work have supported her position on this subject. In her clinic, parents discuss all aspects of their child's condition, confident in the knowledge that they are not only talking to a professional but to a parent who has lived their experience. Her deep understanding of the challenges they face puts her advice in a class of its own. |

| enzyme science critical digestion: The Archetype Diet Dana James, 2018-06-05 Discover your unique female archetype to combat emotional eating, lose weight, and become your happiest, healthiest you. In working with thousands of women who wanted to lose weight and change the shape of their bodies, leading nutritionist and functional medicine practitioner Dana James observed a striking trend: no matter how diligent they were in sticking to their diet and exercise plans, old behavioral patterns and self-doubt sabotaged their efforts. In The Archetype Diet, James helps readers escape the seemingly endless psychological tug-of-war that is hampering their ability to care for themselves and explains which hormones cause you to store body fat on your belly, thighs and hips, and what to eat to change it. A revolutionary, holistic approach to weight loss, this book guides in readers in discovering which of four archetypes they embody: · The Nurturer is always there to care for others. She is kind and compassionate, but this can come at the expense of her own self-care. · The Wonder Woman bases her self-worth on her accomplishments. She is ambitious and driven, but her work often takes precendent over her diet. · The Femme Fatale is sensual, strong, and alluring but can become obsessed with her looks to the point that she develops an unhealthy relationship with food. · The Ethereal is spiritual and intuitive, but highly sensitive to her environment so she tends to eat to numb her reactions to the world. By becoming attuned to your archetype, James shows how you can alter your diet to help feed your unique body chemistry while simultaneously examining how your sense of self-worth shapes your behaviors—including what you eat—in ways that may be working against your goals. Offering recipes, a ten-day meal plan, and a step-by-step psychological intervention, The Archetype Diet will put you on the path to becoming leaner, stronger, and more attuned to your feminine fire and energy. |

| enzyme science critical digestion: The Chemistry of Microbiomes National Academies of Sciences, Engineering, and Medicine, Division on Earth and Life Studies, Board on Chemical Sciences and Technology, Chemical Sciences Roundtable, 2017-07-19 The 21st century has witnessed a complete revolution in the understanding and description of bacteria in eco- systems and microbial assemblages, and how they are regulated by complex interactions among microbes, hosts, and environments. The human organism is no longer considered a monolithic assembly of tissues, but is instead a true ecosystem composed of human cells, bacteria, fungi, algae, and viruses. As such, humans are not unlike other complex ecosystems containing microbial assemblages observed in the marine and earth environments. They all share a basic functional principle: Chemical communication is the universal language that allows such groups to properly function together. These chemical networks regulate interactions like metabolic exchange, antibiosis and symbiosis, and communication. The National Academies of Sciences, Engineering, and Medicine's Chemical Sciences Roundtable organized a series of four seminars in the autumn of 2016 to explore the current advances, opportunities, and challenges toward unveiling this chemical dark matter and its role in the regulation and function of different ecosystems. The first three focused on specific ecosystemsâ€earth, marine, and humanâ€and the last on all microbiome systems. This publication summarizes the presentations and discussions from the seminars. |

| enzyme science critical digestion: Interdisciplinary Approaches to Food Digestion Ourania Gouseti, Gail M. Bornhorst, Serafim Bakalis, Alan Mackie, 2019-02-13 For the first time, this singular and comprehensive text presents a focus on quantitative studies aiming to describe food digestion and the tools that are available for quantification. A case study relevant to real-world applications places this theoretical knowledge in context and demonstrates the different ways digestion studies can be used to develop food products. Interdisciplinary Approaches to Food Digestion undertakes a multidisciplinary approach to food digestion studies, placing them in context and presenting relevant phenomena plus the challenges and limitations of different approaches. This book presents a unique, useful reference work to scientists, students, and researchers in the area of food science, engineering, and nutrition. Over the last two decades there has been an increasing demand for foods that deliver specific nutritional values. In addition, the dramatic increase of food related diseases such as obesity requires the development of novel food products that control satiety and glycemic response. Overall, digestion studies are gaining increasing attention in recent years, especially as the link between diet and health/well-being becomes more evident. However, digestion is a complex process involving a wide range of disciplines such as medicine, nutrition, chemistry, materials science, and engineering. While a significant body of work exists within each discipline, there is a lack of a multidisciplinary approach on the topic which will provide a holistic view of the process. With Interdisciplinary Approaches to Food Digestion, researchers are finally presented with this much needed approach. |
| enzyme science critical digestion: Fiber Fueled Will Bulsiewicz, MD, 2020-05-12 The instant New York Times, USA Today, and Publisher's Weekly bestseller A bold new plant-based plan that challenges popular keto and paleo diets, from an award-winning gastroenterologist. The benefits of restrictive diets like paleo and keto have been touted for more than a decade, but as renowned gastroenterologist Dr. Will Bulsiewicz, or Dr. B, illuminates in this groundbreaking book, the explosion of studies on the microbiome makes it abundantly clear that elimination diets are in fact hazardous to our health. What studies clearly now show--and what Dr. B preaches with his patients--is that gut health is the key to boosting our metabolism, balancing our hormones, and taming the inflammation that causes a host of diseases. And the scientifically proven way to fuel our guts is with dietary fiber from an abundant variety of colorful plants. Forget about the fiber your grandmother used to take--the cutting-edge science on fiber is incredibly exciting. As Dr. B explains, fiber energizes our gut microbes to create powerhouse postbiotics called short-chain fatty acids (SCFAs) that are essential to our health. SCFAs are scientifically proven to promote weight loss, repair leaky gut, strengthen the microbiome, optimize the immune system, reduce food sensitivities, lower cholesterol, reverse type 2 diabetes, improve brain function, and even prevent cancer. Restrictive fad diets starve the gut of the critical fiber we need, weaken the microbes, and make our system vulnerable. As a former junk-food junkie, Dr. B knows firsthand the power of fiber to dramatically transform our health. The good news is that our guts can be trained. Fiber-rich, real foods--with fruits, vegetables, whole grains, seeds, nuts, and legumes--start working quickly and maintain your long-term health, promote weight loss, and allow you to thrive and feel great from the inside out. With a 28-day jumpstart program with menus and more than 65 recipes, along with essential advice on food sensitivities, Fiber Fueled offers the blueprint to start turbocharging your gut for lifelong health today. |

| enzyme science critical digestion: The Gastrointestinal Circulation Peter R. Kvietys, 2010 The microcirculation of the gastrointestinal tract is under the control of both myogenic and metabolic regulatory systems. The myogenic mechanism contributes to basal vascular tone and the regulation of transmural pressure, while the metabolic mechanism is responsible for maintaining an appropriate balance between O2 demand and O2 delivery. In the postprandial state, hydrolytic products of food digestion elicit a hyperemia, which serves to meet the increased O2 demand of nutrient assimilation. Metabolically linked factors (e.g., tissue pO2, adenosine) are primarily responsible for this functional hyperemia. The fenestrated capillaries of the gastrointestinal mucosa are relatively permeable to small hydrolytic products of food digestion (e.g., glucose), yet restrict the transcapillary movement of larger molecules (e.g., albumin). This allows for the absorption of hydrolytic products of food digestion without compromising the oncotic pressure gradient governing transcapillary fluid movement and edema formation. The gastrointestinal microcirculation is also an important component of the mucosal defense system whose function is to prevent (and rapidly repair) inadvertent epithelial injury by potentially noxious constituents of chyme. Two pathological conditions in which the gastrointestinal circulation plays an important role are ischemia/reperfusion and chronic portal hypertension. Ischemia/reperfusion results in mucosal edema and disruption of the epithelium due, in part, to an inflammatory response (e.g., increase in capillary permeability to macromolecules and neutrophil infiltration). Chronic portal hypertension results in an increase in gastrointestinal blood flow due to an imbalance in vasodilator and vasoconstrictor influences on the microcirculation. Table of Contents: Introduction / Anatomy / Regulation of Vascular Tone and Oxygenation / Extrinsic Vasoregulation: Neural and Humoral / Postprandial Hyperemia / Transcapillary Solute Exchange / Transcapillary Fluid Exchange / Interaction of Capillary and Interstitial Forces / Gastrointestinal Circulation and Mucosal Defense / Gastrointestinal Circulation and Mucosal Pathology I: Ischemia/Reperfusion / Gastrointestinal Circulation and Mucosal Pathology II: Chronic Portal Hypertension / Summary and Conclusions / References / Author Biography |

| enzyme science critical digestion: Plant-Environment Interactions František Baluška, 2009-03-03 Our image of plants is changing dramatically away from passive entities merely subject to environmental forces and organisms that are designed solely for the accumulation of photosynthate. Plants are revealing themselves to be dynamic and highly sensitive organisms that actively and competitively forage for limited resources, both above and below ground, organisms that accurately gauge their circumstances, use sophisticated cost-benefit analysis, and take clear actions to mitigate and control diverse environmental threats. Moreover, plants are also capable of complex recognition of self and non-self and are territorial in behavior. They are as sophisticated in behavior as animals but their potential has been masked because it operates on time scales many orders of magnitude less than those of animals. Plants are sessile organisms. As such, the only alternative to a rapidly changing environment is rapid adaptation. This book will focus on all these new and exciting aspects of plant biology. |
