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.

Two questions could not be avoided in the avant-propos of this book; (i) what is the importance to man of ruminant livestock, and (ii) what results of practical relevance in the growing mountain of scientific verbiage could be found in the Proceedings of this Symposium. Herbivores are an integral and critical part of the natural ecosystem which must be preserved because of their impact on human welfare. Wh at makes ruminants especially important to man is that they can thrive on fibrous forage and are thus the only viable enterprise over much of the earth's surface where crop growing is impracti cable. They contribute a wide array of products in addition to 50000 000 tonnes ofmeat (1977) and represent a 'capital reserve' that can be drawn upon in times of emergency: milk for example (450000000 tonnes) can make the difference between subsistence and starvation. About 60% of the world's meat and 80 % of the milk are produced by one third of the world ruminant population in the developed regions and as much as 99 % of the power for agriculture is provided by the ruminant population in developing countries. For the next two decades, a probable increase by 30 % for . cattle and buffalo and more than 40 % for sheep and goats is expected by improving health, fertility, nutrition and genetic potential rather than feed resources.

The B vitamins are eight water-soluble vitamins that play important roles in cell metabolism. Historically, the B vitamins were once thought to be a single vitamin, referred to as Vitamin B (much like how people refer to Vitamin C or Vitamin D). Later research showed that they are chemically distinct vitamins that often coexist in the same foods. Supplements containing all eight B vitamins are generally referred to as a vitamin B complex. Individual B vitamin supplements are referred to by the specific name of each vitamin (e.g. B1, B2, B3). The B vitamins often work together to deliver a number of health benefits to the body. B vitamins have been shown to: support and increase the rate of metabolism; maintain healthy skin and muscle tone; enhance immune and nervous system function; promote cell growth and division -- including that of the red blood cells that help prevent anemia. Together, they also help combat the symptoms and causes of stress, depression, and cardiovascular disease. All B vitamins are water soluble, and are dispersed throughout the body. They must be replenished daily with any excess excreted in the urine. Vitamin B deficiency can lead to an enormous group of health problems. This book presents new and important research in the field.

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.

Almost every aspect of energy and nutrient metabolism is altered by hormonal and other physiological changes during pregnancy and lactation. While it is evident that hormonal adjustments affect nutrient requirements, these are rarely considered when nutrient recommen dations are made for pregnant or lactating women, and often neglected during evaluation of nutritional status. In addition, changes in nutrient metabolism during the stages of pregnancy and oflactation are usually considered separately, while in reality events during pregnancy can have a major influence on nutritional status and nutrient requirements during lactation. The purpose of this volume is to describe changes in the metabolism of important nutrients during pregnancy and lactation, including the physiological basis for these changes and their implications for nutrient requirements and assessment. Authors have considered such issues as inter-relationships between endocrine changes and nutrient metabolism at the tissue, cellular and molecular level; alterations in nutrient binding proteins; the efficiency of nutrient absorp tion and retention; and the impact on maternal as well as fetal nutritional status. Another unique aspect of this book is the focus on pregnancy and lactation as a continuum.

During the last 10-12 years, the research on homocysteine has become very active. About 1500 of articles are now published each year on homocysteine and the vitamins involved in its metabolism. A disturbed homocysteine metabolism can be an underlying factor for pregnancy complications and fetal malformations, cardiovascular disease, dementia, psychiatric and neurologic disorders and possibly carcinogenesis. A disturbed homocysteine metabolism can in most cases be normalised by treatment with folate and/or vitamines B12 and B6. Many of these findings therefore directly concern most practitioners. However, if there are good reviews covering single aspects of this research, these are published in specialised journals. The author has realised the difficulties for the practitioner in keeping updated. This second edition has been thoroughly updated and also offers more data on the vitamins. Over 1600 references are made available.
