  1. .Cholesterol C27H46O
    2. During transport, cholesterol exist often exist as lipoprotein form. which mean a large molecule contain both cholesterol and protein. The good form high density lipoprotein (HDL)contain more protein less lipid and bad form contain more lipid than protein.
    3.it's used to synthiesis steriod hormones. HDL and their protein and lipid constituents also help to inhibit HDL and their protein and lipid constituents help to inhibit oxidation, inflammation, activation of the endothelium, coagulation, and platelet aggregation.
    4.animal product. cheese, egg youls,beef, pork, poultry, fish, shrimp
