Description

The Vitamins: Chemistry, Physiology, Pathology, Methods, Volume VII, Second Edition covers the chemical, physiological, pathological, and methodological aspects of various vitamins. This book is organized around the various vitamins with the physical, chemical, microbiological, and animal assays for each vitamin being discussed in a single chapter. This volume contains 11 chapters and begins with a survey of the principles, procedure, and other general considerations of microbiological assay. The succeeding nine chapters demonstrate the extraction and analysis of various vitamins, including ascorbic acid, thiamine, riboflavin, niacin, vitamin B6, pantothenic acid, folic acid, vitamin B12, and biotin. The concluding chapter looks in to the fundamental principles of nutritional evaluation, with an emphasis on the clinical evaluation of malnutrition.
This book will be of value to nutritionists, dieticians, food scientists, technologists, and researchers.
