Vitamini B7 (Vitamini H/D-Biotin) CAS: 58-85-5 Wogulitsa Wopanga

Biotin ndi yofunikira pakukula kwa maselo, kupanga mafuta acid, komanso kagayidwe ka mafuta ndi ma amino acid. Imagwira ntchito mu citric acid cycle, yomwe ndi njira yomwe mphamvu ya biochemical imapangidwa panthawi yopuma. Biotin ndi coenzyme ya ma enzyme a carboxylase, yomwe imakhudzidwa ndi kupanga mafuta acid, isoleucine, ndi valine, komanso mu gluconeogenesis. Monga coenzyme ya phthalocyanine coenzyme A, Biotin imagwira ntchito popanga mafuta acid, zomwe zimapangitsa kuti glycine CoA ipangidwe. Kuchitapo kanthu ndi gawo loyamba pakupanga mafuta acid, kenako kudzera mu cytoplasmic multi-enzyme complex ndi fatty acid synthase imapanga palmitic acid kuchokera ku phthalocyanine-CoA. Pakukulitsa unyolo wa kaboni mu fatty acid, propanedio phthalide-ACP imagwira ntchito mu kuchitapo kanthu ngati wopereka dicarbon unit, ndipo dipropyl phthalide-ACP imachokera ku phthalide-CoA. Zikuoneka kuti biotin ndi yofunikira pakupanga mafuta acids ndi kukulitsa unyolo wa kaboni mu mafuta acid. Kusowa kwa biotin kungayambitse kagayidwe ka mafuta m'thupi kosayenera, zomwe zimapangitsa kuti thupi lisinthe kapangidwe ka mafuta acids.
