ClassSmall Molecule
Description20a,22b-Dihydroxycholesterol belongs to the class of organic compounds known as trihydroxy bile acids, alcohols and derivatives. These are prenol lipids structurally characterized by a bile acid or alcohol which bears three hydroxyl groups. 20a,22b-Dihydroxycholesterol is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 20a,22b-Dihydroxycholesterol participates in a number of enzymatic reactions, within cattle. In particular, 20a,22b-Dihydroxycholesterol can be converted into pregnenolone and 4-methylpentanal through the action of the enzyme cholesterol side-chain cleavage enzyme, mitochondrial. In addition, 20a,22b-Dihydroxycholesterol can be biosynthesized from 22b-hydroxycholesterol through the action of the enzyme cholesterol side-chain cleavage enzyme, mitochondrial. In cattle, 20a,22b-dihydroxycholesterol is involved in the metabolic pathway called the steroidogenesis pathway.
