물리적 성질

Appearance: biotin is a white crystalline substance. Stability: it is fairly stable to air, heat, and light in dry form. In solution, however, it tends to degrade under strongly acidic or basic conditions. In the eight possible stereoisomers of biotin, only the (+)-isomer (called d-biotin) has biological activity. Biotin is covalently bound to its enzymes by an amide bond to the ε-amino group of a lysine residue and C-2 of the thiophane nucleus. The biotin molecule is activated by polarization of the O and N-1’atoms of the ureido nucleus. This leads to increased nucleophilicity at N-1′, which promotes the formation of a covalent bond between the electrophilic car bonyl phosphate formed from bicarbonate and ATP, and allows biotin to serve as a transport agent for CO2.

용도

biotin (biotine; vitamin B7/vitamin H) is anti-seborrhoeic. Some cosmetic manufacturers claim biotin has healing properties and as such, is a good ingredient for treating acne skin. Biotin is also part of the B complex group of vitamins (specifically vitamin B7). A deficiency of this vitamin has been associated with greasy scalp and baldness. Its deficiency in humans is considered extremely rare, and the value of external applications through the use of cosmetic products is questionable.
