Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
Cobalamin (vitamin B12) was discovered in the first half of the 20th century. Vast amount of information on the role of the vitamins in human health and disease became available. Cobalamin science was, however, based on theoretical concepts that have been accepted without further proof of facts and hypotheses. Recently, the breath-taking pace of development in research technologies has changed our understanding for the role of nutrients and the complex interaction between diet, environment and diseases. Conditions like aging, diet and drugs increase the risk of developing cobalamin deficiency, probably because of diminished ability to liberate, absorb or distribute the food-derived vitamin. From a basic science point of view, understanding of the transport and function of the vitamin, may pave the road for using this system for drug delivery. This book represents up-to-date literature on the discoveries and developments in the field of cobalamin. It includes multifaceted aspects of the vitamin in health and disease conditions. The book has been written by leading scientists who have significant contributions in this field and represents therefore, a timely unique encyclopaedia on cobalamin.

Book Description
Comprehensive Biochemistry, Volume 21: Metabolism of Vitamins and Trace Elements focuses on the processes, reactions, methodologies, and principles involved in the metabolism of vitamins and trace elements, including catabolism, enzymatic synthesis, absorption, and metabolic functions. The selection first elaborates on the biosynthesis of thiamine and riboflavin and metabolism of vitamin B6. Topics include absorption and transport of vitamin B6, catabolism of vitamin B6, mechanism of riboflavin synthetase from yeast, enzymatic synthesis of thiamine, biogenesis of thiazole, and interconversion of various forms of vitamin B6. The book also ponders on the biosynthesis of pantothenic acid and coenzyme A and metabolism of biotin, analogues, folic acid, pteridine derivatives, and cobalamins. Discussions focus on the uses of radioactive cobalamins in metabolic studies, absorption of cobalamins, pteroylpolyglutamates, and biosynthesis of folate compounds, interconversions, and degradations. The manuscript examines the metabolism and metabolic function of trace elements, including iron, zinc, copper, manganese, molybdenum, selenium, fluorine, and iodine. The selection is a vital source of data for researchers interested in the metabolism of vitamins and trace elements.
