The Esterase, cholesterol, with the CAS registry number 9026-00-0, is also known as Cholesterin esterase. It belongs to the product category of Enzymes. Its EINECS number is 232-808-6. Its EC number is 3.1.1.13. Its classification code is TSCA Flag XU [Exempt from reporting under the Inventory Update Rule]. In enzymology, it is an enzyme that catalyzes the chemical reaction: a steryl ester + H₂O a sterol + a fatty acid. Thus, the two substrates of this enzyme are steryl ester and H₂O, whereas its two products are sterol and fatty acid. This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is steryl-ester acylhydrolase. Other names in common use include choleSterol esterase, cholesteryl ester synthase, triterpenol esterase, cholesteryl esterase, cholesteryl ester hydrolase, sterol ester hydrolase, cholesterol ester hydrolase, cholesterase, and acylcholesterol lipase. This enzyme participates in bile acid biosynthesis. It should be sealed and stored in a ventilated and dry place. Moreover, it should be protected from light. You should not breathe dust. When using it, you must avoid contact with eyes.
