Carboxylesterase 1/CES1: Proteins and Enzymes

Carboxylesterase 1 hydrolyzes ester- and amide bonds of substrates ranging from small molecule esters such as phenylester to long-chain fatty acid esters and thioesters. It plays a major role in the pharmacokinetic behavior of many therapeutic agents containing an ester. Through de-esterification, it participates in the detoxification of drugs such as cocaine and heroin in serum and liver.
