7-Dehydrocholesterol CAS 434-16-2
ʻO 7-Dehydrocholesterol he pauka keʻokeʻo keʻokeʻo, he pauka kristal melemele māmā, hoʻokaʻawale ʻia a lawe ʻia mai ka ʻili puaʻa. Hiki ke loaʻa iā ia ma ka esterification, bromination, elimination, a me ka hydrolysis o ka cholesterol. Ka helu heheʻe 150-151 ℃ (anhydrous). [α] 20/D-113.6 ° (chloroform). Hiki ke ʻike ʻia i ka ea i ka oxidation. ʻO kahi kikowaena lāʻau lapaʻau i hoʻohui ʻia e ka hopena saponification o 7-dehydrocholesterol. ʻO 7-dehydrocholesterol (7-DHC) he 5,7-conjugated diene sterol a me kahi precursor no ka biosynthesis cholesterol

Hoʻohana nui ʻia ʻo 7-Dehydrocholesterol ma ke ʻano he koʻikoʻi koʻikoʻi no ka synthesis o ka vitamina D3 a ma ke ʻano he mea hoʻohui i ka mālama ʻili, pale i ka lā, a me nā mea hoʻonaninani. ʻO 7-dehydrocholesterol (7-DHC) he 5,7-conjugated diene sterol a me kahi precursor no ka biosynthesis cholesterol. Ke ʻike ʻia i ka radiation ultraviolet B (UVB), kōkua ia i ka hana ʻana o ka huaʻa D3. ʻO 7-dehydrocholesterol kahi maʻamau kūloko no ka hoʻoholo ʻana i nā sterols a hoʻohana pū ʻia e like me nā reagents ʻē aʻe.
Hoʻopili pinepine ʻia i 25kg / pahu, 50kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
