Cholesterol is an important indicator of clinical biochemical examination. Under normal circumstances, the cholesterol synthesized by the body in the liver and taken from food will be converted into a component of cell membranes, and keep the concentration of cholesterol in the blood constant . When the liver is severely diseased, cholesterol levels decrease. In patients with jaundice obstruction and nephrotic syndrome, cholesterol levels tend to rise.

1.1.It is an important raw material for using as an emulsifier.

2.Cholesterol in nature is mainly found in animal foods. A few plants have cholesterol, and most plants have a substance structurally similar to cholesterol-plant sterols. Phytosterols have no atherogenic effect. In the intestinal mucosa, phytosterols (especially sitosterol) can competitively inhibit cholesterol absorption.
