Metabolite Identification
Common Name Delta 8,14 -Sterol
Description Delta 8,14 -Sterol is an intermediate in the biosynthesis of steroids (KEGG ID C11508), and is converted from O butusifoliol via the enzyme cytochrome P450, family 51, subfamily A (sterol 14-demethylase) [EC:]. It is then converted to 4-alpha-methylfecosterol via the enzyme delta14-sterol reductase [EC:].
