Chemical Information
FooDB Namezymosterol
DescriptionZymosterol, also known as 5alpha-cholesta-8,24-dien-3beta-ol or delta8,24-cholestadien-3beta-ol, belongs to cholesterols and derivatives class of compounds. Those are compounds containing a 3-hydroxylated cholestane core. Thus, zymosterol is considered to be a sterol lipid molecule. Zymosterol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Zymosterol can be synthesized from 5alpha-cholestane. Zymosterol is also a parent compound for other transformation products, including but not limited to, 4beta-methylzymosterol-4alpha-carboxylic acid, 3-dehydro-4-methylzymosterol, and zymosterol intermediate 1b. Zymosterol can be found in a number of food items such as squashberry, hard wheat, salmonberry, and loquat, which makes zymosterol a potential biomarker for the consumption of these food products. Zymosterol exists in all eukaryotes, ranging from yeast to humans. In humans, zymosterol is involved in several metabolic pathways, some of which include zoledronate action pathway, alendronate action pathway, pravastatin action pathway, and atorvastatin action pathway. Zymosterol is also involved in several metabolic disorders, some of which include cholesteryl ester storage disease, lysosomal acid lipase deficiency (wolman disease), smith-lemli-opitz syndrome (SLOS), and chondrodysplasia punctata II, X linked dominant (CDPX2). Zymosterol is an intermediate in cholesterol biosynthesis. Disregarding some intermediate compounds (e.g. 4-4-dimethylzymosterol) lanosterol can be considered a precursor of zymosterol in the cholesterol synthesis pathway. The conversion of zymosterol into cholesterol happens in the endoplasmic reticulum. Zymosterol accumulates quickly in the plasma membrane coming from the cytosol. The movement of zymosterol across the cytosol is more than twice as fast as the movement of cholesterol itself .
