3. Vitamins
 The word vitamin comes from Greek word (vitamine) means vital
for life .
 A vitamin is an organic molecule (or a set of molecules closely
related chemically, i.e. vitamers) that is an essential
micronutrient that an organism needs in small quantities for the
proper functioning of its metabolism.
 Essential nutrients cannot be synthesized in the organism, either
at all or not in sufficient quantities, and therefore must be
obtained through the diet.
