Vitamins are complex organic compounds required by the body in small quantities to maintain good health. They are not synthesized by the body and must be obtained through diet. Casimir Funk first coined the term "vitamin" in 1911 to describe these essential micronutrients. Vitamins are classified as either fat-soluble - vitamins A, D, E, and K, which can be stored in fat - or water-soluble - vitamins including C and B vitamins, which dissolve in water and cannot be stored, so must be replenished daily. The document goes on to provide details on the chemical names, functions and deficiency symptoms of both fat-soluble and water-soluble vitamins.

2. VITAMINS
The vitamins are a group of complex organic compounds
required in small quantities by the body for the maintenance of
good health. They are not normally synthesized in the body and
hence are to be supplied through the diet (Food).
Casimir Funk, a Warsaw-born biochemist was the first to coin the word
"vitamin" in 1911

3. Classification of vitamins
 Vitamins are classified by their solubility.
 Fat-soluble vitamins are vitamins that dissolve in fat.
Because fat is easily stored in your body, fat-soluble
vitamins can be stored within your fat. This means they can
accumulate and be saved for later use. The fat-soluble
vitamins are A, D, E and K.
 Water-soluble vitamins, which are vitamins that dissolve in
water. Because your body is a watery environment, these
vitamins can move through your body pretty easily, and they
can also be flushed out in your urine with ease. So, your
body does not store water-soluble vitamins, and you need to
replenish them daily.
