Metabolite Identification
Common Name4,4-dimethyl-5alpha-cholesta-8,14-dien-3beta-ol
Description4,4-dimethyl-8,14-cholestadien-3beta-ol, also known as 4,4-dcdo or T-MAS, belongs to the class of organic compounds known as cholesterols and derivatives. Cholesterols and derivatives are compounds containing a 3-hydroxylated cholestane core. Thus, 4,4-dimethyl-8,14-cholestadien-3beta-ol is considered to be a sterol lipid molecule. 4,4-dimethyl-8,14-cholestadien-3beta-ol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
