nature : animals can be divided into two sterols and plant sterols, which is also known as biliary cholesterol sterols, found in animal organs within. The latter mainly sitosterol, and stigmasterol, ergosterol alcohols such as vegetable oil sterols.

Sterols molecular structure from four rings, in a 17-location chain; The different sterols, branched-chain length and structure is different. Sterols are white lamellae. Pharmaceuticals and cosmetics raw materials.
