What is a Vitamin ?
A vitamin is an organic molecule (or a group of chemically related molecules, known as vitamers) that is a crucial micronutrient that a living thing need in minute amounts for the proper operation of its metabolism. Essential nutrients must be received from diet since they cannot be manufactured by the organism, either completely or in adequate amounts. Some species can synthesis vitamin C, but not others; in the second case, vitamin C is the term used to describe it. The three further categories of important nutrients—minerals, essential fatty acids, and essential amino acids—are not included in the term "vitamin." The majority of vitamins are vitamers, which are collections of closely similar molecules.
