Etymology[edit]

From German Ester, perhaps a contraction or abstraction of Essigäther (ethyl acetate), from Essig (vinegar) (from Latin acetum) and Äther (ether). See ether for more.

Pronunciation[edit]

Noun[edit]

ester (plural esters)

  1. (organic chemistry) 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 joined via carbon to another oxygen atom.
    • 1991, Malcolm B. Hale et al., “New Products and Markets for Menhaden, Brevoortia spp.”, in Marine Fisheries Review, volume 53, number 4, page 47:
      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 is cooled overnight.
    • 1991, W. F. Kean, C. J. L. Lock, and H. E. Howard-Lock, “Chirality in antirheumatic drugs”, in The Lancet, volume 338, DOI:10.1016/0140-6736(91)92382-C, page 1567:
      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–propionic-acid hybrid would be able to cross lipid membranes such as the blood–brain barrier.
    • 1996, Steven Ashley, “Composite car structures pass the crash test”, in Mechanical Engineering[1], volume 118, number 12, page 60:
      The effort’s primary material systems are vinyl esters and polyurethanes, reinforced with inexpensive chopped-glass rovings. Automated glass-fiber preforming processes and high-rate molding procedures are being studied in an effort to reduce cycle times and production costs substantially.
