Cholesterolester hydrolase,

Cholesterol Cholesterolester-hydrolase + Chol-esteroloxidase (double reaction) Cholest-4-en-3-one, h2o2 Na2HP04 NaH2P04 pH 6.8 Iodide 50-400 mg %... 

IUPAC classification of the enzyme has been cither EC.3.1.1.1 (carboxylester hydrolase) or EC. 3. LI.13 (cholesterolester hydrolase) (TbWe 2). 

Pancreatic carboxylester lipase, secreted by the pancreas as an active enzyme without proteolytic activation, displays broad substrate specificity and has therefore received many names in the literature carboxylesterase, bile salt-stimulated (or activated or dependent) lipase (due to its absolute requirement for bile salts to hydrolyze insoluble substrates), carboxylester lipase or hydrolase, cholesterol esterase, lysophospholipase, nonspecific lipase, and monoglyceride lipase. The IUPAC classification of the enzyme has been either EC.3.1.1.1 (carboxylester hydrolase) or EC.3.1.1.13 (cholesterolester hydrolase) (Table 2).
