A thioester is a compound derived from carboxylic acids where the oxygen atom in the carbonyl group (C=O) is replaced by a sulfur atom. It plays a crucial role in biochemical processes and nucleophilic acyl substitution reactions in organic chemistry.
An organic compound containing a carboxyl group (COOH), which consists of one carbon atom double-bonded to an oxygen atom and single-bonded to another oxygen atom that is also bonded to a hydrogen atom.
A reaction mechanism where a nucleophile displaces another group attached to an acyl (carbon-oxygen double bond) group of a carboxylic acid derivative.
