ester

 [es´ter]
a compound formed from an alcohol and an acid by removal of water.

es·ter

(es'tĕr),
An organic compound containing the grouping, -X(O)-O-R (X = carbon, sulfur, phosphorus, etc.; R = radical of an alcohol), formed by the elimination of H2O between the -OH of an acid group and the -OH of an alcohol group; usually written as in ethyl acetate (from acetic acid and ethyl alcohol), CH3CO-OC2H5 or CH3COOC2H5.

ester

[es′tər]
Etymology: Ger, Essigäther, acetic ether
a class of chemical compounds formed by the bonding of an alcohol and one or more organic acids, with the loss of a water molecule for each ester group formed. Fats are esters, produced by the bonding of fatty acids with the alcohol glycerol.

Patient discussion about ester

Q. Does anyone know an over the counter alternative to Lovaza, omega-3 acid ethyl esters? too expensive at Dr
