| Publisher Description: Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A vitamin is an organic compound required as a nutrient in tiny amounts by an organism. In other words, an organic chemical compound is called a vitamin when it cannot be synthesized in sufficient quantities by an organism, and must be obtained from the diet. Vitamins are classified by their biological and chemical activity, not their structure. Thus, each "vitamin" refers to a number of vitamer compounds that all show the biological activity associated with a particular vitamin. Such a set of chemicals are grouped under an alphabetized vitamin "generic descriptor" title, such as "vitamin A," which includes the compounds retinal, retinol, and four known carotenoids. Vitamins have diverse biochemical functions. This book studies fat soluble vitamins including retinol, ergosterol, vitamin D5, tocopherol, and menadione.
