Codsiga

7-Dehydrocholesterol waxaa inta badan loo isticmaalaa dhexdhexaad muhiim ah oo loogu talagalay isku-darka fitamiin D3 iyo sidoo kale wax lagu daro daryeelka maqaarka, ilaalinta qorraxda, iyo qurxinta. 7-dehydrocholesterol (7-DHC) waa sterol diene ah oo 5,7-isku xiran waana horudhac u ah biosynthesis-ka kolestaroolka. Marka la soo bandhigo shucaaca ultraviolet B (UVB), waxay gacan ka geysataa soo saarista fitamiin D3. 7-dehydrocholesterol waa halbeeg gudaha ah oo lagu go'aamiyo sterols-ka waxaana sidoo kale loo isticmaalaa sidii reagents kale oo shaybaar.
