olein n. 甘油之油酸脂,脂肪之液状部份 甘油之油酸脂,脂肪之液状部份 olein n 1: a naturally occurring glyceride of oleic acid that is found in fats and oils [synonym: {triolein}, {olein}] Olein \O"le*in\ ([=o]"l[-e]*[i^]n), n. [L. oleum oil: cf. F.
ol['e]ine.] (Physiol. Chem.) A fat, liquid at ordinary temperatures, but solidifying at temperatures below 0[deg] C., found abundantly in both the animal and vegetable kingdoms (see {Palmitin}). It dissolves solid fats, especially at 30-40[deg] C. Chemically, olein is a glyceride of oleic acid; and, as three molecules of the acid are united to one molecule of glycerol to form the fat, it is technically known as {triolein}. It is also called {elain}. [1913 Webster]
