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.
Water-soluble vitamins. Water-soluble vitamins travel freely through the body, and excess amounts usually are excreted by the kidneys. The body needs water-soluble vitamins in frequent, small doses. These vitamins are not as likely as fat-soluble vitamins to reach toxic levels.But niacin, vitamin B6, folate, choline, and vitamin C have upper consumption limits.Vitamin B6 at high levels over a long period of time has been shown to cause irreversible nerve damage.ater-soluble vitamins travel freely through the body, and excess amounts usually are excreted by the kidneys.
