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.

ester linkage,
n the bonding between fatty acids and glycerol that characterizes true fats.

Patient discussion about ester

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

A. there are all sort of companies that sell Omega-3, i buy from a company named Alsepa, but there are dozens of companies. but don't be tempted to buy a very cheap one, because they can be less purified.
