Biotin, also known as vitamin H or coenzyme R, is a water-soluble B-vitamin (vitamin B7). It is composed of a ureido (tetrahydroimidizalone) ring fused with a tetrahydrothiophene ring. A valeric acid substituent is attached to one of the carbon atoms of the tetrahydrothiophene ring. Biotin is a coenzyme for carboxylase enzymes, involved in the synthesis of fatty acids, isoleucine, and valine, and in gluconeogenesis. The only human health condition for which there is strong evidence of biotin's potential benefit as a treatment is biotin deficiency.
Most of them dissolve in water and are called water-soluble vitamins. In contrast, there are only four fat-soluble vitamins, which dissolve in oil (liquid fat). Nine water-soluble vitamins are found in the human diet: Vitamin B1 (thiamine) Vitamin B2 (riboflavin) Vitamin B3 (niacin) Vitamin B5 (pantothenic acid) Vitamin B6; Vitamin B7 (biotin) Vitamin B9
