Metabolite Identification
Common Name4α-methyl-cholesta-8-enol
Description4alpha-methyl-5alpha-cholest-8-en-3beta-ol, also known as methost-8-enol or 4α-methylcholesta-8-en-3β-ol, belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. Thus, 4alpha-methyl-5alpha-cholest-8-en-3beta-ol is considered to be a sterol lipid molecule. 4alpha-methyl-5alpha-cholest-8-en-3beta-ol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
