Common Name27-Hydroxycholesterol
Description27-Hydroxycholesterol, also known as cholest-5-ene-3b,27-diol, 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, 27-hydroxycholesterol is considered to be a sterol lipid molecule. 27-Hydroxycholesterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Within humans, 27-hydroxycholesterol participates in a number of enzymatic reactions. In particular, 27-hydroxycholesterol can be biosynthesized from cholesterol through the action of the enzyme 25-hydroxycholesterol 7-alpha-hydroxylase. In addition, 27-hydroxycholesterol can be converted into 7-a,27-dihydroxycholesterol through the action of the enzyme cholesterol 7-alpha-monooxygenase. In humans, 27-hydroxycholesterol is involved in the metabolic disorder called familial hypercholanemia (fhca). 27-Hydroxycholesterol is a potentially toxic compound. 27-Hydroxycholesterol was first documented in 1986 (PMID: 3795956). A 27-Hydroxycholesterol in which the 25-position has R-configuration (PMID: 14729854) (PMID: 11504730) (PMID: 10832098) (PMID: 12719428).
