The enzyme sterol esterase (EC 3.1.1.13) catalyzes the reaction a sterol ester + H 2 O ⇌ {\displaystyle \rightleftharpoons } a sterol + a fatty acid This enzyme belongs to the family of hydrolases , specifically those acting on carboxylic ester bonds.
Cholesterol is a sterol, a steroid-like lipid made by animals, including humans.The human body makes one-eighth to one-fourth teaspoons of pure cholesterol daily. A cholesterol level of 5.5 millimoles per litre or below is recommended for an adult.
Increased levels of cholesteryl ester have been found in certain parts of the brain of people with Huntington's disease. Higher concentrations of cholesteryl ester have been found in the caudate and putamen , but not the cerebellum , of people with Huntington disease compared with levels in controls. [ 4 ]
Sterols and related compounds play essential roles in the physiology of eukaryotic organisms, and are essential for normal physiology of plants, animals, and fungi. [4] For example, cholesterol forms part of the cellular membrane in animals, where it affects the cell membrane's fluidity and serves as secondary messenger in developmental signaling.
Sterol esters are a heterogeneous group of chemical compounds. They are created when the hydroxyl group of a sterol and a fatty acid undergo an esterification reaction. They can be found in trace amounts in every cell type but are highly enriched in foam cells and are common components of human skin oil .

What is the Normal Testosterone Level for a 70-Year-Old Man? 156–819 ng/dL. The researchers also broke the data down into normal levels of free testosterone and bioavailable testosterone.
Cholesterol is the principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils. [3] [4]Cholesterol is biosynthesized by all animal cells [citation needed] and is an essential structural and signaling component of animal cell membranes.
