Esterase is widely present in organisms, such as helping to digest esters in food in the digestive system, and also participating in biological processes such as fatty acid metabolism within cells. Esterase is widely used in industry, such as in the production of biodiesel, food additives, and cosmetics. ≥15U /mg powder, ≥100 U/mg protein. Source: Porcine liver. Properties The molecular weight of esterase monomer is approximately 66kDa. It is a serine enzyme with two active sites on each molecule, which dissociates into active half molecules in the presence of dilute acid or concentrated salt Stability Esterase acts on water-soluble carboxylic acid esters containing short chain fatty acids. Its function comes from the catalytic triad of Ser, His, and Asp/Glu, which is stable in the form of a triad under low temperature and low pH conditions. Application 1、Used for kinetic resolution and asymmetric synthesis in organic chemistry. 2、Used to reveal fluorescence in the UV visible spectrum. 3、Used in pharmaceutical and industrial applications to catalyze the hydrolysis of pentaacetyl catechins and epicatechin. 4、It is used to develop an alternative experimental scheme based on gel for screening bead binding catalytic activity in aqueous media. Attention 1、 Avoid contact with skin and eyes. 2、 For your safety and health, please wear Lab coat and disposable gloves.
