一般描述
Cholesterol Esterase is a serine hydrolase released from the exocrine pancreas. It belongs to the α/β hydrolase family of enzymes.
应用
Cholesterol Esterase from porcine pancreas has been used:
- in an in vitro simulated digestion model to improve the hydrolysis of carotenoid esters in the intestinal phase
- to analyze the bioavailability of phytosterol and cholesterol in the aqueous micellar phase of an in vitro simulated digestion model
- as a standard in enzyme activity assay
生化/生理作用
For the hydrolysis of cholesterol esters in the determination of total cholesterol in serum or plasma; Application in (selective) hydrolysis/condensation of carboxylic ester bonds
Cholesterol esterase exhibits broad substrate specificity and regulates the bile salt-mediated hydrolysis of dietary cholesteryl esters. It participates in the hydrolysis of triglycerides and phospholipids which are essential for normal cholesterol absorption. Cholesterol esterase plays a key role in transporting free cholesterol to enterocytes. Loss of enzyme function reduces the intestinal absorption of dietary cholesteryl esters.
