General description
Zymosterol-d5 is the deuterated form of zymosterol. Zymosterol is a precursor of cholesterol and the synthesis events occur in rough endoplasmic reticulum.
Application
Zymosterol-d5 has been used as a standard in liquid chromatography–mass spectrometry (LC-MS) for quantification of sterols from human plasma samples.
Biochem/physiol Actions
Zymosterol is a substrate for 24-dehydrocholesterol reductase. It acts as a methyl acceptor and exists as fatty acid ester aerobically-grown yeast cells.

Where examined, cholesterol is synthesized in the endoplasmic reticulum; however, its precursor, zymosterol, is found mostly in the plasma membrane. The novel implication of these disparate findings is that zymosterol circulates within the cell. In tracing its movements, we have

In order to identify the methyl acceptor for the methylation of sterol side-chains in ergosterol biosynthesis, Saccharomyces cerevisiae (wild type) was grown in the presence and absence of ethionine which was expected to be an inhibitor of the methylation. Gas-liquid

Cytochrome P450 46A1 (CYP46A1) converts cholesterol to 24-hydroxycholesterol and thereby controls the major pathways of cholesterol removal from the brain. Cyp46a1-/- mice have a reduction in the rate of cholesterol biosynthesis in the brain and significant impairments to memory and
