Metabolite Identification
Common Name4,4-Dimethylcholesta-8,14,24-trienol
Description4,4-Dimethylcholesta-8,14,24-trienol is a product of the enzyme delta14-sterol reductase [EC 1.3.1.70] (KEGG). It is involved in the biosynthesis of steroids and is involved in the conversion of lanosterol to zymosterol. In particular, lanosterol 14-alpha-demethylase, catalyzes the C-14 demethylation of lanosterol to form 4,4-Dimethylcholesta-8,14,24-trienol in the ergosterol biosynthesis pathway. It is thought to be a meiosis activating sterol.
