Fiitamiin B7 (Fiitamiin H/D-Biotin) CAS:58-85-5 Alaab-qeybiye Soo-saare

Biotin waa lagama maarmaan u ah koritaanka unugyada, soo saarista asiidhyada dufanka leh, iyo dheef-shiid kiimikaadka dufanka iyo amino acids. Waxay door ka ciyaartaa wareegga citric acid, kaas oo ah habka loo sameeyo tamarta bayoolaji inta lagu jiro neefsashada aerobic. Biotin waa coenzyme loogu talagalay ensaymada carboxylase, oo ku lug leh isku-darka asiidhyada dufanka leh, isoleucine, iyo valine, iyo gluconeogenesis. Iyada oo ah coenzyme oo ah phthalocyanine coenzyme A, Biotin waxay ku lug leedahay isku-darka asiidhyada dufanka leh, taasoo kicisa sameynta glycine CoA. Falcelintu waa tallaabada ugu horreysa ee isku-darka asiidhyada dufanka leh, ka dibna iyada oo loo marayo cytoplasmic multi-enzyme complex iyo fatty acid synthase waxay soo saaraan asiidh palmitic ah oo ka yimaada phthalocyanine-CoA. Kordhinta silsiladda kaarboon ee ku jirta asiidhka dufanka leh, propanedio phthalide-ACP waxay ku lug leedahay falgalka iyada oo ah deeq-bixiye cutubka dicarbon, dipropyl phthalide-ACP-na waxaa laga soo qaatay phthalide-CoA. Waxaa la arki karaa in biotin uu lagama maarmaan u yahay isku-darka asiidhyada dufanka leh iyo fidinta silsiladaha kaarboon ee ku jira asiidhyada dufanka leh. Yaraanta biotin waxay horseedi kartaa dheef-shiid kiimikaad aan caadi ahayn oo ku jira dufanka, taasoo keenta isbeddello ku yimaada qaab-dhismeedka asiidhyada dufanka leh ee jirka.
