-Vitamin
-The term vitamin is derived from the word vitamin, which was coined in 1912 by Polish biochemist Casimir Funk, who isolated a complex of micronutrients essential to life, all of which he presumed to be amines. Hence, Option 3 is correct.
-Vitamins are organic compounds that are required in small amounts in our diet but their deficiency causes specific diseases.
-Most of the vitamins cannot be synthesized in our body but plants can synthesize almost all of them, so they are considered essential food factors.
-However, the bacteria of the gut can produce some of the vitamins required by us.
-All the vitamins are generally available in our diet. Different vitamins belong to various chemical classes and it is difficult to define them based on structure.
-They are generally regarded as organic compounds required in the diet in small amounts to perform specific biological functions for normal maintenance of optimum growth and health of the organism.
-Vitamins are designated by alphabets A, B, C, D, etc. Some of them are further named as sub-groups e.g. B1, B2, B6, B12, etc.
-The term “Vitamine” was coined from the word vital + amine since the earlier identified compounds had amino groups.
