Comprehensive Biochemisty, Volume 11: Water-Soluble Vitamins, Hormones, Antibiotics deals with the organic and physical chemistry of the major organic constituents of living material. This book provides a sound treatment of the important biological high polymers, emphasizing their shape and physical properties. A number of substances peculiar to plants, certain isoprenoids, flavonoids, tannins, lignins, and plant hormones are also covered. This publication likewise discusses the fate of thiamine in living organisms, biologically active isoalloxazines, and auxins with a heterocyclic ring system. Other topics include the yolk-formation hormone of the corpora allata, biochemical aspect of the antibiotics, and miscellaneous antibiotics derivable from amino acids. This volume is a good source for biochemists and specialists conducting work on water-soluble vitamins, hormones, and antibiotics.
The first demonstration of the existence of a vitamin and the full recognition of this fact are often attributed to the work of McCollum, who found that a sub stance in butterfat and cod-liver oil was necessary for growth and health of ani mals fed purified diets. It became obvious that an organic substance present in microconcentrations was vital to growth and reproduction of animals. Following the coining of the word vitamine by Funk, McCollum named this fat-soluble sub stance vitamin A. We can, therefore, state that vitamin A was certainly one of the first known vitamins, yet its function and the function of the other fat-soluble vitamins had remained largely unknown until recent years. However, there has been an explosion of investigation and new information in this field, which had remained quiescent for at least two or three decades. It is now obvious that the fat-soluble vitamins function quite differently from their water-soluble counter parts. We have learned that vitamin D functions by virtue of its being converted in the kidney to a hormone that functions to regulate calcium and phosphorus metabolism. This new endocrine system is in the process of being elucidated in detail, and in addition, the medical use of these hormonal forms of vitamin D in the treatment of a variety of metabolic bone diseases has excited the medical com munity.
Vitamins in Endocrine Metabolism covers the problems of nutritional diseases in the fields of endocrinology, pathology, enzymology, and vitamin research. This book is divided into 11 chapters that discuss the conditions affecting vitamin requirements. The introductory chapters deal with the intracellular localization, synthesis, molecular structure, and reaction rate of enzymes. The succeeding chapters examine the methods of analysis and mode of action of hormones; pathology of vitamin A deficiency in man and animals; description of vitamin B complex; and diseases of vitamin C deficiency. Other chapters explore the modifying effects of the diet and availability of enzymic activators, as well as the biochemical aspects of isoenzymes, pre-enzymes, coenzymes, and enzyme cofactors. A chapter highlights the characteristics of vitamin, while another chapter is devoted to the chemical structure of vitamin E and the essential fatty acids. The final chapters focus on the exogenous chemical carcinogen. The book can provide useful information to doctors, nutritionists, students, and researchers.
This volume is the newest release in the authoritative series of quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. Dietary Reference Intakes (DRIs) is the newest framework for an expanded approach developed by U.S. and Canadian scientists. This book discusses in detail the role of vitamin C, vitamin E, selenium, and the carotenoids in human physiology and health. For each nutrient the committee presents what is known about how it functions in the human body, which factors may affect how it works, and how the nutrient may be related to chronic disease. Dietary Reference Intakes provides reference intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for different groups based on age and gender, along with a new reference intake, the Tolerable Upper Intake Level (UL), designed to assist an individual in knowing how much is "too much" of a nutrient.
Diet and Health examines the many complex issues concerning diet and its role in increasing or decreasing the risk of chronic disease. It proposes dietary recommendations for reducing the risk of the major diseases and causes of death today: atherosclerotic cardiovascular diseases (including heart attack and stroke), cancer, high blood pressure, obesity, osteoporosis, diabetes mellitus, liver disease, and dental caries.
The use of drugs in food animal production has resulted in benefits throughout the food industry; however, their use has also raised public health safety concerns. The Use of Drugs in Food Animals provides an overview of why and how drugs are used in the major food-producing animal industriesâ€"poultry, dairy, beef, swine, and aquaculture. The volume discusses the prevalence of human pathogens in foods of animal origin. It also addresses the transfer of resistance in animal microbes to human pathogens and the resulting risk of human disease. The committee offers analysis and insight into these areas: Monitoring of drug residues. The book provides a brief overview of how the FDA and USDA monitor drug residues in foods of animal origin and describes quality assurance programs initiated by the poultry, dairy, beef, and swine industries. Antibiotic resistance. The committee reports what is known about this controversial problem and its potential effect on human health. The volume also looks at how drug use may be minimized with new approaches in genetics, nutrition, and animal management.
Vitamin C holds a unique place in scientific and cultural history. In this book, a group of leading scientific researchers describe new insights into the myriad ways vitamin C is employed during normal physiological functioning. In addition, the text provides an extensive overview of the following: the rationale for utilizing vitamin C in the clinic, updates on recent uses of vitamin C in cancer treatment through high-dose intravenous therapies, the role vitamin C plays in the treatment of sepsis and infectious disease, management of the ways vitamin C can improve stem cell differentiation, as well as vitamin C use in other important health situations. Features Includes chapters from a team of leading international scholars Reviews the history and recent research on the functions, benefits, and uses of vitamin C Focuses special attention on the way vitamin C can be used in the treatment of cancers Discusses how vitamin C can be employed against infectious disease
Since 1941, Recommended Dietary Allowances (RDAs) has been recognized as the most authoritative source of information on nutrient levels for healthy people. Since publication of the 10th edition in 1989, there has been rising awareness of the impact of nutrition on chronic disease. In light of new research findings and a growing public focus on nutrition and health, the expert panel responsible for formulation RDAs reviewed and expanded its approachâ€"the result: Dietary Reference Intakes. This new series of references greatly extends the scope and application of previous nutrient guidelines. For each nutrient the book presents what is known about how the nutrient functions in the human body, what the best method is to determine its requirements, which factors (caffeine or exercise, for example) may affect how it works, and how the nutrient may be related to chronic disease. This volume of the series presents information about thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, pantothenic acid, biotin, and choline. Based on analysis of nutrient metabolism in humans and data on intakes in the U.S. population, the committee recommends intakes for each age groupâ€"from the first days of life through childhood, sexual maturity, midlife, and the later years. Recommendations for pregnancy and lactation also are made, and the book identifies when intake of a nutrient may be too much. Representing a new paradigm for the nutrition community, Dietary Reference Intakes encompasses: Estimated Average Requirements (EARs). These are used to set Recommended Dietary Allowances. Recommended Dietary Allowances (RDAs). Intakes that meet the RDA are likely to meet the nutrient requirement of nearly all individuals in a life-stage and gender group. Adequate Intakes (AIs). These are used instead of RDAs when an EAR cannot be calculated. Both the RDA and the AI may be used as goals for individual intake. Tolerable Upper Intake Levels (ULs). Intakes below the UL are unlikely to pose risks of adverse health effects in healthy people. This new framework encompasses both essential nutrients and other food components thought to pay a role in health, such as dietary fiber. It incorporates functional endpoints and examines the relationship between dose and response in determining adequacy and the hazards of excess intake for each nutrient.
