WebBiotin, also known as vitamin B 7 or vitamin H, is an essential vitamin because it acts as a cofactor for five biotin-dependent carboxylases that play critical roles in the intermediate metabolism of gluconeogenesis, fatty acid synthesis, and amino acid catabolism. 1 Pharmacology and pathophysiology of biotin have been discussed in Chapter 2.The … WebThe effect of biotin binding on streptavidin (STV) structure and stability was studied using differential scanning calorimetry, Fourier transform infrared spec-troscopy (FT-IR), and …
Biotin is classified as a heterocyclic compound, with a sulfur-containing ring fused ureido and tetrahydrothiophene group. A C5-carboxylic acid side chain is appended to one of the rings. The ureido ring, containing the −N−CO−N− group, serves as the carbon dioxide carrier in carboxylation reactions. Biotin is a coenzyme for five carboxylase enzymes, which are involved in the catabolism of amino acids and fatty acids, synthesis of fatty acids, and gluconeogenesis.
