Cholesteryl butyrate (Cholesterol butyrate) is a steroid alcohol that is essentially insoluble in aqueous solutions. In mammals, it is normally solubilized by its association with other lipids, such as phospholipids or bile acids thus, most cholesterol is found in cell membranes, plasma lipoproteins, and bile. Cholesterol can be esterified with a fatty acid to form cholesteryl esters. The latter form discrete lipid droplets in cells, especially in cells of steroidogenic tissues, and in the lipid core of low-density lipoproteins in the blood. Cholesterol is a fatty lipid sparingly insoluble in water but soluble in a number of organic solvents.
