Compare the tetracyclic ring structure of this assembled molecular model of cholesterol to those of progesterone & testosterone. Cholesterol contributes to cell membrane fluidity, permeability & stability, properties limited in relatively inflexible plant cell walls.
Cholesterol is an essential precursor or intermediate compound mammals use to produce steroid hormones, vitamin D and bile acids. The latter are produced in the liver and are important for the absorption of fat-soluble vitamins A, D, E and K in the small intestine.
