83-46-5 Usage

Definition

sterol: Any of a group of steroidbasedalcohols having a hydrocarbonside-chain of 8–10 carbon atoms.Sterols exist either as free sterols oras esters of fatty acids. Animal sterols(zoosterols) include cholesterol andlanosterol. The major plant sterol(phytosterol) is beta-sitosterol, whilefungal sterols (mycosterols) includeergosterol.

Purification Methods

Crystallise -sitosterol from EtOH, MeOH, Me2CO, Me2CO/EtOH or Me2CO/MeOH. It has also been purified by zone melting. The acetate crystallises from MeOH or EtOH as plates with m 127128o and [] D 20 -41o (c 2, CHCl3). The benzoate crystallises from EtOH as needles with m 146-147o and [] D 20 –13.8o (c 2, CHCl3).

Uses

A common sterol in plants. Isolated from wheat germ oil, corn oil. Antilipemic. Used in the treatment of prostatic adenoma.

Chemical Properties

White powder

Uses

antiinflammatory, immunomodulator

Definition

ChEBI: A phytosterols that is stigmast-5-ene substituted by a beta-hydroxy group at position 3.

Definition

A steroid with long aliphatic side chains (8–10 carbons) and at least one hydroxyl group. They are lipidsoluble and often occur in membranes. Examples are cholesterol and ergosterol.
