7-Dehydrocholesterol CAS 434-16-2
He pauka kristal keʻokeʻo ka 7-Dehydrocholesterol, he pauka kristal melemele māmā, i hoʻokaʻawale ʻia a unuhi ʻia mai ka ʻili puaʻa. Hiki ke loaʻa iā ia ma o ka esterification, bromination, elimination, a me ka hydrolysis o ka cholesterol. Helu heheʻe 150-151 ℃ (anhydrous). [α] 20/D-113.6 ° (chloroform). ʻO ka mea i hōʻike ʻia i ka lewa he mea maʻalahi ia i ka oxidation. He mea waena lāʻau lapaʻau i synthesized ʻia e ka hopena saponification o 7-dehydrocholesterol. ʻO 7-dehydrocholesterol (7-DHC) he 5,7-conjugated diene sterol a he mea mua no ka biosynthesis cholesterol.
| Mea | Nā kikoʻī |
| Kikowaena paila | 451.27°C (manaʻo kikoʻī) |
| Ka nui o ka paʻa | 0.9717 (kuhikuhi maʻamau) |
| Kiko heheʻe | 148-152 °C (mālamalama ʻia) |
| Nā kūlana mālama | -20°C |
| ke kū'ē ʻana | 1.5100 (kuhikuhi) |
Hoʻohana nui ʻia ʻo 7-Dehydrocholesterol ma ke ʻano he mea waena koʻikoʻi no ka hana ʻana o ka huaora D3 a ma ke ʻano he mea hoʻohui i ka mālama ʻili, ka pale ʻana i ka lā, a me nā mea hoʻonani. ʻO 7-dehydrocholesterol (7-DHC) kahi 5,7-conjugated diene sterol a he mea mua no ka biosynthesis cholesterol. Ke hōʻike ʻia i ka radiation ultraviolet B (UVB), hāʻawi ia i ka hana ʻana o ka huaora D3. ʻO 7-dehydrocholesterol kahi maʻamau kūloko no ka hoʻoholo ʻana i nā sterols a hoʻohana ʻia hoʻi e like me nā reagents hale hana ʻē aʻe.
Hoʻopili pinepine ʻia i 25kg/pahu, 50kg/pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
