    • 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...
    • 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...
    • 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...

Origin

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.
