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.
Sterol is an organic compound [1] with formula C 17 H 28 O , whose molecule is derived from that of gonane by replacement of a hydrogen atom on C3 position by a hydroxyl group.

This list contains a list of EC numbers for the third group, EC 3, hydrolases, placed in numerical order as determined by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology.
In biochemistry, an esterase is a class of enzyme that splits esters into an acid and an alcohol in a chemical reaction with water called hydrolysis (and as such, it is a type of hydrolase). A wide range of different esterases exist that differ in their substrate specificity, their protein structure , and their biological function.
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 .

For example, a key intermediate for the fungal hormone trisporic acid was made by its alkylation [5] and it has been used to make sterols. [6] Other authors have used it in inverse-electron-demand Diels–Alder reactions leading to sesquiterpene dimers [ 7 ] or in reactions forming simple derivatives.
