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.

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.

The evolution of C[O.sub.2] results from the decarboxylation of ester linkage, and the water formation may correspond to the dehydration between hydroxy end groups formed through hydrolysis of ester linkage (31).
Specifically, tannins have antioxidant properties by cleaving ester linkages through hydrolysis.[17] Cleaving ester linkages by hydrolysis are synonymous to breaking down of large aggregates into smaller subunits, and ergo energy is used up and not excessively stored lowering contributing mass in the body.[25] Furthermore, assessment of the different groups shows that the high dose of E.
Among these elastomers, the highest performance elastomers are thermoplastic polyester elastomers (TPE-E), also known as COPE and TPC-ET, which are essentially copolyether esters with alternating, random-length sequences of either long-chain or short-chain oxyalkalene glycols connected by ester linkages. Typically, the hard segments are composed of multiple short chain ester units, such as tetramethylene terephthalate units, and the soft segments are derived from aliphatic polyether and polyester glycols (ref.
