ester

A compound most often formed by the condensation of an alcohol and an acid, with elimination of water, which contains the functional group carbon-oxygen double bond (i.e., carbonyl) joined via carbon to another oxygen atom.

• To produce a test material containing at least 75 percent omega-3 polyunsaturates, the menhaden triglycerides are transesterified to produce fatty acid ethyl esters. The esters are reacted with urea dissolved in hot ethanol and the solution
• The thiol-coenzyme-A ester formed by R-arylpropionic acid can bind to triglyceride to form a “hybrid” triglyceride: such hybrid triglycerides can cause alteration of fatty-acid metabolism and membrane function, and a lipophilic triglyceride
