What is Cholesterol?. A waxy substance – technically a sterol (unsaturated steroid alcohol). 75% of your cholesterol is made in your liver, the rest is absorbed from food. Cholesterol travels in particles called lipoproteins: high-density lipoproteins (HDL) and low-Density Lipoproteins (LDL). FromEgg. Yolk. Cholesterol. Is the most abundant . steroid. in the body..

Cholesterol is an essential lipid constituent of cell membranes. Cholesterol is a precursor of steroid hormones and of bile acids. Intermediates of cholesterol biosynthesis are required to make vitamin D and for posttranslational modification of membrane proteins. Ray . Hreiche. (updated slides from . Mohana. .
