General description
β-sitosterol is a phytosterol (plant sterol) found in a wide variety of plants, including pecans, saw palmetto, avocados, pumpkin seed, rice bran, wheat germ, and soybeans. Chemically resembling cholesterol, phytosterols inhibit the absorption of cholesterol. Phytosterols have also been shown to have anticancer properties
Sitosterol, also called as β-sitosterol, is synthesized through the mevalonate and deoxy xylulose pathways. Synthetically, it is synthesized from stigmasterol by Δ22–23 alkene group hydrogenation. Structurally sitosterol differ from cholesterol with ethyl (sitosterol) group in C24 position of side chain(65). Sitosterol is a lipid component of membranes. It corresponds to a molecular mass of 414.71 g/mol).
Application
Sitosterol has been used as a sterol compound to test its interaction with human Mincle protein. It has also been used as a component of erythrocyte lipid model membrane for biophysical studies.
Biochem/physiol Actions
Sitosterol promotes the antioxidant levels and is used as an effective anti-inflammatory, antiapoptotic and anticancer agent in medicinal preparations. It acts as a neutralizing agent for the venom from viper and cobra. Sitosterol acts on protein kinase C (PKC) and in the sphingomyelin cycle to mediate tumor progression inhibition.

Elevated levels of plasma LDL cholesterol (LDL-C) represent a major risk factor for cardiovascular disease. Treatments aimed at reducing levels of circulating LDL are regarded, therefore, as cardioprotective. The cholesterol lowering properties of plant sterols have been known for some
