Constitutional Formula: 



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.


Main Functions:

biotin is involved in important metabolic pathways such as gluconeogenesis, fatty acid synthesis, and amino acid catabolism. 

Biotin regulates the catabolic enzyme propionyl-CoA carboxylase at the posttranscriptional level whereas the holo-carboxylase

synthetase is regulated at the transcriptional level
