A class of enzymes that catalyze the hydrolysis of one of the three ester bonds in a phosphotriester-containing compound.

An ester bond is the bond between an alcohol group (-OH) and a carboxylic acid group (-COOH), formed by the elimination of a molecule of water (H 2 O). Previous definition Ester

An ester is an organic compound where the hydrogen in the compound's carboxyl group is replaced with a hydrocarbon group. Esters are derived from carboxylic acids and (usually) alcohol.

Carboxylic esters hydrolyse to the parent carboxylic acid and an alcohol. In both cases it is the C-O bond between the acyl group and the oxygen that is 

Fatty acids are poorly water soluble due to saturated covalent bonds between carbons while the carboxyl terminal end can interact with water or other molecules  An ester bond is the bond between an alcohol group (-OH) and a carboxylic acid group (-COOH), formed by the elimination of a molecule of water (H2O). In  Sep 12, 2006 presence of BBr3. Alternatively, the catalytic method of dealkylation of a phosphate ester bond containing compound may be de?ned as  Esters are a functional group commonly encountered in organic chemistry. They are characterized by a carbon bound to three other atoms: a single bond to a carbon, a double bond to an oxygen, and a single bond to an oxygen.

Similar to Amides,  Carboxylic esters hydrolyse to the parent carboxylic acid and an alcohol. In both cases it is the C-O bond between the acyl group and the oxygen that is  av J Arnling Bååth · 2016 · Citerat av 36 — The Glucuronoyl esterases (GE) have been proposed to target lignin-carbohydrate (LC) ester bonds between lignin moieties and glucuronic acid side groups of  The effects of self-assembly on the hydrolysis kinetics of surfactants that contain ester bonds are discussed.
