Download or read book Activation and Detoxification Enzymes written by Chang-Hwei Chen and published by Springer Science & Business Media. This book was released on 2011-11-16 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans are exposed to foreign compounds such as drugs, household products and environmental chemicals by swallowing or breathing. Also, food is considered a foreign compound. Such foreign compounds can be non-essential and non-functional to life, and commonly are referred to as xenobiotics. Some xenobiotics are not toxic; however, many of them are potentially toxic or become toxic after conversion to metabolic intermediates. A considerable number of foreign compounds belong to non-polar, lipophilic substances. Lipophilic compounds are not soluble in water. Metabolic conversion of lipophilic foreign compounds to facilitate their removal from the body is essentially carried out by biochemical reactions catalyzed by two classes of metabolizing enzymes, namely, activation enzymes and detoxification enzymes. Activation enzyme-catalyzed functionalization reaction introduces a functional group to a lipophilic compound. Functionalization modifies many foreign compounds to form reactive intermediates capable of interacting with cellular components (proteins, DNA and lipids), leading to a variety of conditions for diseases. Functionalized compounds are further metabolized through detoxification enzyme-catalyzed reactions, which result in an increase in the solubility of parent compounds and an inactivation of metabolic intermediates, thus facilitating their excretion from the body. To minimize the exposure of potentially toxic metabolic intermediates, it is essential to keep them at a minimum level. Extensive investigations have revealed that foreign compound-metabolizing enzymes exhibit genetic polymorphisms. Variations in their activities can produce different results as to the susceptibility to potential toxic effects. Moreover, the expressions of activation enzymes and detoxification enzymes are inducible. A number of chemical compounds are capable of acting as modulators for these two classes of enzymes. These findings have lead to the proposal of modulating metabolizing enzymes as a useful approach for human health benefits. Importantly, many of these chemical compounds are present in human daily diets. There are many advances that have been made in the past decades towards the understanding of functions and implications of activation enzymes and detoxification enzymes. An organized, concise overview is needed for the readers who are initially exposed to this important subject, particularly for students and researchers in the areas of biomedical sciences, biochemistry, nutrition, pharmacology and chemistry. This book is intended to serve this purpose as an introduction to the subject. Furthermore, major topics in the book, excluding catalytic reactions and structural properties, may have interest to other readers who have knowledge of basic sciences and understanding enzyme related information. The book discusses subjects associated with foreign compound metabolizing enzymes with emphasis on biochemical aspects, including lipophilic foreign compounds, catalytic properties, reactive intermediates, biomedical and biochemical effects, genetic polymorphisms, enzyme inducibility, enzyme modulation for health benefits, dietary related enzyme modulators, and structural characteristics of enzyme inducers.
Download or read book Oxidants in Biology written by Giuseppe Valacchi and published by Springer Science & Business Media. This book was released on 2008-06-06 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidants, like other aspects of life, involves tradeoffs. Oxidants, whether intentionally produced or by-products of normal metabolism can either mediate a variety of critical biological processes but when present inappropriately cause extensive damage to biological molecules (DNA, proteins, and lipids). These effects can lead to either damage that is a major contributor to aging and degenerative diseases (or to other diseases such as cancer, cardiovascular disease, immune-system decline, brain dysfunction, and cataracts) or normal physiological function- tissue repair, defense against pathogens and cellular proliferation. On the other hand the body is equipped with a complex antioxidant/oxidant handling system which includes both enzymatic and nonenzymatic (i.e. small molecules such as flavonoids, ascorbate, tocopherol, and carotenoids) produced endogenously or derived from the diet. This book focuses on how the same molecules can have favorable or noxious effects depending on location, level and timing. Each chapter focuses on one particular molecule or oxidant/antioxidant system and provides a state of the art review of the current understanding regarding both positive and negative actions of the system under review.
