Organized into 11 chapters, this book begins with an overview of the processes by which the main nutrients are broken down into simpler components. This text then explores the existence in foodstuffs of substances essential for the proper functioning of the animal organism. Other chapters consider the synthetic method of producing a commercially important chemical to be displaced by a method based on its isolation from natural sources. This book discusses as well the effect of various vitamin deficiencies in human beings. The final chapter deals with the series of changes that represents the biochemical reactions that occur during the contraction of muscles. This book is a valuable resource for biochemists and clinicians.

Introduction to Enzyme and Coenzyme Chemistry

Introduction to Enzyme and Coenzyme Chemistry PDF Author: T. D. H. Bugg
Publisher: John Wiley & Sons
ISBN: 1118348990
Category : Science
Languages : en
Pages : 310

Book Description
Enzymes are giant macromolecules which catalyse biochemical reactions. They are remarkable in many ways. Their three-dimensional structures are highly complex, yet they are formed by spontaneous folding of a linear polypeptide chain. Their catalytic properties are far more impressive than synthetic catalysts which operate under more extreme conditions. Each enzyme catalyses a single chemical reaction on a particular chemical substrate with very high enantioselectivity and enantiospecificity at rates which approach “catalytic perfection”. Living cells are capable of carrying out a huge repertoire of enzyme-catalysed chemical reactions, some of which have little or no precedent in organic chemistry. The popular textbook Introduction to Enzyme and Coenzyme Chemistry has been thoroughly updated to include information on the most recent advances in our understanding of enzyme action, with additional recent examples from the literature used to illustrate key points. A major new feature is the inclusion of two-colour figures, and the addition of over 40 new figures of the active sites of enzymes discussed in the text, in order to illustrate the interplay between enzyme structure and function. This new edition provides a concise but comprehensive account from the perspective of organic chemistry, what enzymes are, how they work, and how they catalyse many of the major classes of enzymatic reactions, and will continue to prove invaluable to both undergraduate and postgraduate students of organic, bio-organic and medicinal chemistry, chemical biology, biochemistry and biotechnology.

Dietary Reference Intakes for Vitamin C, Vitamin E, Selenium, and Carotenoids

Dietary Reference Intakes for Vitamin C, Vitamin E, Selenium, and Carotenoids PDF Author: Institute of Medicine
Publisher: National Academies Press
ISBN: 0309069491
Category : Medical
Languages : en
Pages : 530

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.

Comprehensive Chirality

Comprehensive Chirality PDF Author:
Publisher: Newnes
ISBN: 0080951686
Category : Science
Languages : en
Pages : 5635

Book Description
Although many books exist on the subject of chiral chemistry, they only briefly cover chiral synthesis and analysis as a minor part of a larger work, to date there are none that pull together the background information and latest advances in one comprehensive reference work. Comprehensive Chirality provides a complete overview of the field, and includes chiral research relevant to synthesis, analytic chemistry, catalysis, and pharmaceuticals. The individual chapters in each of the 9 volumes provide an in depth review and collection of references on definition, technology, applications and a guide/links to the related literature. Whether in an Academic or Corporate setting, these chapters will form an invaluable resource for advanced students/researchers new to an area and those who need further background or answers to a particular problem, particularly in the development of drugs. Chirality research today is a central theme in chemistry and biology and is growing in importance across a number of disciplinary boundaries. These studies do not always share a unique identifying factor or subject themselves to clear and concise definitions. This work unites the different areas of research and allows anyone working or researching in chiral chemistry to navigate through the most essential concepts with ease, saving them time and vastly improving their understanding. The field of chirality counts several journals that are directly and indirectly concerned with the field. There is no reference work that encompasses the entire field and unites the different areas of research through deep foundational reviews. Comprehensive Chirality fills this vacuum, and can be considered the definitive work. It will help users apply context to the diverse journal literature offering and aid them in identifying areas for further research and/or for solving problems. Chief Editors, Hisashi Yamamoto (University of Chicago) and Erick Carreira (ETH Zürich) have assembled an impressive, world-class team of Volume Editors and Contributing Authors. Each chapter has been painstakingly reviewed and checked for consistent high quality. The result is an authoritative overview which ties the literature together and provides the user with a reliable background information and citation resource.

The Fat-Soluble Vitamins

The Fat-Soluble Vitamins PDF Author: H. DeLuca
Publisher: Springer Science & Business Media
ISBN: 1461588707
Category : Science
Languages : en
Pages : 297

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.

Brain, Behaviour, and Iron in the Infant Diet

Brain, Behaviour, and Iron in the Infant Diet PDF Author: John Dobbing
Publisher: Springer Science & Business Media
ISBN: 1447117662
Category : Medical
Languages : en
Pages : 203

Book Description
Iron deficiency in infancy is very widespread, even in developed countries and even when there is no general malnutrition. This book examines the question whether iron deficiency in early life leads to deleterious changes in brain and/or behavioural development. Each of the nine contributors comments critically on each of the other eight chapters, so that the book is very extensively peer-reviewed. The evidence is set out so that the reader may make his own informed judgement. Iron deficiency could very easily be prevented; this fact is of prime importance if such deficiency has long-lasting effects on human intellectual capacity and achievement.
