Olein

[әuliin]

解释:

(n.) A fat, liquid at ordinary temperatures, but solidifying at temperatures below 0¡ C., found abundantly in both the animal and vegetable kingdoms (see Palmitin). It dissolves solid fats, especially at 30-40¡ C. Chemically, olein is a glyceride of oleic acid; and, as three molecules of the acid are united to one molecule of glyceryl to form the fat, it is technically known as triolein. It is also called elain.
