Wikamina B7 (Wikamina H/D-Biotin) CAS:58-85-5 Mea Hana Mea Hoʻolako

Pono ʻo Biotin no ka ulu ʻana o nā cell, ka hana ʻana o nā waikawa momona, a me ka metabolism o nā momona a me nā waikawa amino. He kuleana kona i loko o ke kaʻina hana o ka citric acid, ʻo ia ke kaʻina hana e hoʻoulu ʻia ai ka ikehu biochemical i ka wā o ka hanu aerobic. He coenzyme ʻo Biotin no nā enzymes carboxylase, i komo i ka synthesis o nā waikawa momona, isoleucine, a me valine, a ma ka gluconeogenesis. Ma ke ʻano he coenzyme o ka phthalocyanine coenzyme A, pili ʻo Biotin i ka synthesis o nā waikawa momona, e hoʻoulu ana i ka hoʻokumu ʻana o glycine CoA. ʻO ka hopena ka hana mua i ka synthesis o nā waikawa momona, a laila ma o ka cytoplasmic multi-enzyme complex a me ka fatty acid synthase synthesize palmitic acid mai ka phthalocyanine-CoA. I ka hoʻolōʻihi ʻana o ke kaulahao kalapona i loko o ka waikawa momona, pili ka propanedio phthalide-ACP i ka hopena ma ke ʻano he mea hāʻawi o ka dicarbon unit, a ua loaʻa ka dipropyl phthalide-ACP mai ka phthalide-CoA. Hiki ke ʻike ʻia he pono ka biotin no ka synthesis o nā waikawa momona a me ka hoʻolōʻihi ʻana o nā kaulahao kalapona i loko o ka waikawa momona. Hiki i ka hemahema o ka biotin ke alakaʻi i ka metabolism lipid maʻamau, e hopena ai i nā loli o ka haku mele momona i loko o ke kino.
