7-Dehydrocholesterol CAS 434-16-2
7-Dehydrocholesterol waa budo crystalline cad, budo crystalline jaale khafiif ah, go'doonsan oo laga soo saaray maqaarka doofaarka. Waxa kale oo lagu heli karaa esterification, bromination, baabi'inta, iyo hydrolysis of kolestaroolka. Barta dhalaalka 150-151 ℃ (anhydrous). [α] 20/D-113.6 ° (chloroform). Soo gaabinta hawada waxay u nugul tahay oksaydheynta. Dhexdhexaadka dawooyinka ee lagu farsameeyay falcelinta saponification ee 7-dehydrocholesterol. 7-dehydrocholesterol (7-DHC) waa 5,7-isku-dhafan sterol diene iyo horudhac u ah biosynthesis kolestaroolka

7-Dehydrocholesterol waxaa inta badan loo isticmaalaa dhex dhexaad muhiim u ah isku dhafka fitamiin D3 iyo sida lagu daro daryeelka maqaarka, ilaalinta qorraxda, iyo qurxinta. 7-dehydrocholesterol (7-DHC) waa 5,7-isku-dhafan sterol diene iyo horudhac u ah biosynthesis kolestaroolka. Marka ay la kulmaan shucaaca ultraviolet B (UVB), waxay ka qayb qaadataa soo saarista fitamiin D3. 7-dehydrocholesterol waa halbeeg gudaha ah oo lagu go'aamiyo sterols waxaana sidoo kale loo isticmaalaa sida reagents kale oo shaybaar.
Caadi ahaan waxaa lagu buuxiyaa 25kg / durbaan, 50kg / durbaan, iyo sidoo kale waxaa la samayn karaa xirmo habaysan.
