== Function ==


'''Cholesterol esterase''' (ChoE) also named '''bile-salt activated lipase''' or '''sterol esterase''' catalyzes the hydrolytic cleavage of cholesterol, other sterol esters and triglycerides.<ref>PMID:11563913</ref>


== Disease ==


'''Cholesterol esterase''' (ChoE) also named bile-acid activated lipase catalyzes the hydrolytic cleavage of cholesterol, other sterol esters and triglycerides.  Deficiency of this enzyme causes Wolman’s disease and cholesteryl ester storage disease.
