| Description | 4alpha-Methylzymosterol 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-methylzymosterol is considered to be a sterol lipid molecule. 4alpha-Methylzymosterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, 4alpha-methylzymosterol has been detected, but not quantified in, several different foods, such as redcurrants, sunflowers, robusta coffees, white mustards, and sesbania flowers. This could make 4alpha-methylzymosterol a potential biomarker for the consumption of these foods. 4alpha-Methylzymosterol is an intermediate in the biosynthesis of steroids. It is the seventh to last step in the synthesis of vitamin D2 and is converted from 3-keto-4-methylzymosterol via the enzyme 3-keto steroid reductase (EC 1.1.1.270). It is then converted into zymosterol. |
