Common Name24-Hydroxycholesterol
Description24-Hydroxycholesterol, also known as cholest-5-ene-3,24-diol or cerebrosterol, belongs to the class of organic compounds known as dihydroxy bile acids, alcohols and derivatives. Dihydroxy bile acids, alcohols and derivatives are compounds containing or derived from a bile acid or alcohol, and which bears exactly two carboxylic acid groups. Thus, 24-hydroxycholesterol is considered to be a sterol lipid molecule. 24-Hydroxycholesterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Within humans, 24-hydroxycholesterol participates in a number of enzymatic reactions. In particular, 24-hydroxycholesterol can be biosynthesized from cholesterol; which is mediated by the enzyme cholesterol 24-hydroxylase. In addition, 24-hydroxycholesterol can be converted into (24R)-cholest-5-ene-3-β,7-α,24-triol through the action of the enzyme 24-hydroxycholesterol 7-alpha-hydroxylase. In humans, 24-hydroxycholesterol is involved in bile acid biosynthesis. 24-Hydroxycholesterol, with regard to humans, has been found to be associated with several diseases such as mild cognitive impairment, neuroborreliosis, subarachnoid hemorrhage, and meningitis; 24-hydroxycholesterol has also been linked to the inborn metabolic disorder hypercholesterolemia. 24-Hydroxycholesterol is found in Homo sapiens. 24-Hydroxycholesterol was first documented in 2003 (PMID: 14574622). A 24-hydroxycholesterol that has S configuration at position 24 (PMID: 15061359).
