They are analogous to carboxylate esters (R−C(=O)−O−R’) with the sulfur in the thioester replacing oxygen in the carboxylate ester, as implied by the thio- prefix. They are the product of esterification of a carboxylic acid (R−C(=O)−O−H) with a thiol (R'−S−H). In biochemistry, the best-known thioesters are derivatives of coenzyme A, e.g., acetyl-CoA.
