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
Because diseases of the bone are often less acute and less lifethreatening than dis eases of the circulatory system, gastrointestinal tract, kidney, liver, and the nervous system, they have received a disproportionately smaller amount of attention in the medical world. With the average increasing life span of man as a result of improve ments in modern medicine, espe~ially in the pediatric field, the seriousness of many metabolic bone diseases has indeed become more obvious. In addition, other improvements in medicine, such as hemodialysis for the preservation of renal failure patients, have permitted the development of other consequences of diseased kidneys, one of which is the appearance of renal osteodystrophy. Finally, the appearance of several genetic disorders in the area of metabolic bone disease has been underscored by the solution of other pediatric diseas~s of much more serious consequences. These emerging problems all suggest that much remains to be learned concerning the sys temic control of bone, both as a structural organ and as a reservoir for the important elements of calcium and phosphorus so essential for the support of life in complex multicellular organisms of which man is the most important. As will be demonstrated in the historical portion of this manuscript, the existence of the three most important humoral factors regulating bone metabolism and func tion are now known.

Book Description
This volume represents an interdisciplinary approach to an understanding of the chemistry, physiology, and medical significance of the vitamin riboflavin. Information has been reviewed on the physiological role of the vitamin, the metabolic effects of riboflavin deficiency in animals and man, and the regulation of riboflavin metabolism. In each chapter early background material has been included, but the major emphasis has been on the many recent advances that have been made. The early chapters of the book are concerned with the physical and chemical properties of riboflavin and its coenzyme derivatives and the nature of the interactions between flavoprotein apoenzymes and their coenzymes. The various methods currently available for measuring f1avins in biological tissues, particularly in man, have been described in detail, together with newer procedures that appear to have certain advantages over existing techniques. Chapters dealing with the absorption, excretion, and metabolism of riboflavin provide basic data on the processes involved in vitamin uptake and in metabolic transformations.

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
This single-source reference draws together the current knowledge of the vitamins’ biological properties in the context of human nutrition. Vitamins are co-enzymes, antioxidants or precursors of hormones and are therefore involved in a great many biochemical and physiological processes. They play a vital role in the maintenance of health, and there is evidence that dietary sources of vitamins have beneficial effects in the prevention of heart-related diseases, bone diseases and possibly cancer. Following introductory chapters on historical and nutritional aspects of vitamins, the next four chapters cover relevant and detailed aspects of physiology and functional anatomy, biochemistry, immunology and the regulation of protein synthesis by nuclear hormone receptors. These background chapters, supported by a glossary of terms, provide the scientific principles upon which vitamin functions are based. The following thirteen chapters deal with each vitamin in turn. Subject areas include chemical structure, intestinal absorption, transport, metabolism, biochemical and physiological actions, immunoregulatory properties, deficiency-related diseases and potential toxicity. An extensive bibliography refers the reader to the original research literature. Vitamins is aimed at nutritionists, biochemists, physiologists and physicians whether they be researchers, teachers or students. Food scientists, food technologists and many others working in the health professions will also find much of use and interest in the book. The inclusion of the theoretical principles in the background chapters makes the book an ideal starting point for those working outside the area who need a solid overview of the subject.

Book Description
The Nutrition and Health series of books has as an overriding mission to provide health professionals with texts that are considered essential because each includes: a synthesis of the state of the science; timely, in-depth reviews by the leading researchers in their respective fields; extensive, up-to-date fully annotated reference lists; a detailed index; relevant tables and figures; identification of paradigm shifts and the consequences; of information between chapters, but targeted, inter-chapter refer virtually no overlap rals, suggestions of areas for future research; and balanced, data-driven answers to patient questions that are based on the totality of evidence rather than the findings of any single study. The series volumes are not the outcome of a symposium. Rather, each editor has the potential to examine a chosen area with a broad perspective, both in subject matter as well as in the choice of chapter authors. The international perspective, especially with regard to public health initiatives, is emphasized where appropriate. The editors, whose training is both research and practice oriented, have the opportunity to develop a primary objective for their book, define the scope and focus, and then invite the leading authori ties from around the world to be part of their initiative. The authors are encouraged to provide an overview of the field, discuss their own research, and relate the research de findings to potential human health consequences.
