Ações bioquímicas/fisiológicas

Cholesterol is a lipid that makes up about 20-25% of the structural components of the cell membranes. It determines the fluidity and permeability of the membrane, making it permeable to water but not to ions and protons. Cholesterol also regulates the functions of the transporters and signaling proteins present on the plasma membrane. The major sites of cholesterol synthesis are small intestine and liver.
Major component of all biological membranes; ~25% of total brain lipid is cholesterol.

Nota de preparo

Cholesterol monohydrate yields a clear, colorless to faint yellow solution in hot alcohol. It is also soluble in acetone, dioxane, ethyl acetate, benzene, petroleum ether, oils, fats, and in aqueous solutions of bile salts. Solutions should be protected from light.
