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.

Urine leukocyte esterase trace abnormal can be a sign of an underlying infection or inflammation in the urinary tract. It is important to understand the causes, symptoms, and treatment options for this condition in order to seek appropriate medical care.

The meaning of ESTERASE is an enzyme that accelerates the hydrolysis or synthesis of esters.

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.

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).

Carboxylesterases (CE) are members of the esterase family of enzymes, and as their name suggests, they are responsible for the hydrolysis of carboxylesters into the corresponding alcohol and carboxylic acid.

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.

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.
