desmosterol
Sign in to saveAlso known as 3beta-cholesta-5,24-dien-3-ol, Cholest-5,24-dien-3beta-ol, Cholesta-5,24-dien-3b-ol, Cholesta-5,24-dien-3-ol, (1S,2R,5S,10S,11S,14R,15R)-2,15-dimethyl-14-[(2R)-6-methylhept-5-en-2-yl]tetracyclo[8.7.0.0^{2,7}.0^{11,15}]heptadec-7-en-5-ol
Desmosterol (cholesta-5,24-dien-3β-ol) is a lipid present in the membrane of phytoplankton and an intermediate product in cholesterol synthesis in mammal cells. Structurally, desmosterol has a similar backbone to cholesterol, with the exception of an additional double bond in the structure of desmosterol.

Desmosterol (cholesta-5,24-dien-3β-ol) is a lipid present in the membrane of phytoplankton and an intermediate product in cholesterol synthesis in mammal cells. Structurally, desmosterol has a similar backbone to cholesterol, with the exception of an additional double bond in the structure of desmosterol.
The similarity can be seen biologically through the synthesis of cholesterol in the human body, as desmosterol is the immediate precursor to cholesterol in the Bloch pathway. Desmosterol is accumulated in desmosterolosis and undergoes reduction with the enzyme 24-dehydrocholesterol reductase to form cholesterol.
