In biochemistry, an esterase is a class of enzyme that splits esters into an acid and an alcohol in a chemical reaction with water called hydrolysis (and as such, it is a type of hydrolase). A wide range of different esterases exist that differ in their substrate specificity, their protein structure , and their biological function.

Esterases are structurally diverse family of enzymes that catalyze the addition of a water molecule to an ester to produce an acid and alcohol. An example of esterase action is given in Fig. 1 where butyrylcholinesterase catalyzes hydrolysis of butyrylcholine to butyric acid and choline.

Esterases are defined as enzymes that catalyse the hydrolysis of esters of organic acids, regulating the equilibrium between esters and free acids. Esters are an important group of volatile compounds that can contribute to wine flavour and changes in their concentration have the potential to influence wine quality (Swiegers et al., 2005).

Esterases are enzymes that help break esters into acid and alcohol in aqueous solutions. Furthermore, unlike lipases, esterases hydrolyze short-chain acyl glycerol rather than long-chain acylglycerols.

Esterases, hydrolases which split ester bonds, hydrolyse a number of compounds used as drugs in humans. The enzymes involved are classified broadly as cholinesterases (including acetylcholinesterase), carboxylesterases, and arylesterases, but apart from acetylcholinesterase, their biological function is unknown.

2024年5月21日 · Esterase is a type of enzyme that causes esters to split into an acid and an alcohol within the human body. When these two components are mixed with water, it is called hydrolysis. There are several kinds of esterase. Three factors set each type apart from the others: substrate specificity, biological function, and protein structure.

Esterases (EC 3.1.1.x) represent a diverse group of hydrolases catalyzing the cleavage and formation of ester bonds and are widely distributed in animals, plants and microorganisms. Beside lipases, a considerable number of microbial carboxyl …

Carboxylester hydrolases, commonly named esterases, consist of a large spectrum of enzymes defined by their ability to catalyze the hydrolysis of carboxylic ester bonds and are widely distributed among animals, plants, and microorganisms.

Esterases are a class of enzymes that split esters into an acid and an alcohol in a chemical reaction with water, having high potential in pharmaceutical, food and biofuel industrial applications.

2005年1月4日 · Esterases are employed in dairies, and for the production of wine, fruit juices, beer, and alcohol. In order to transform low value fats and oils into more valuable ones, esterases as well as lipases are used as trans-esterification catalysts.
