    • n Olein (Physiol. Chem) 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 glycerol to form the fat, it is technically known as triolein. It is also called elain.

    • n olein One of the most widely distributed of the natural fats, the trioleic ether of glycerol, having the formula C3H5(C18H33O2)3. It is a colorless oil at ordinary temperatures, with little odor and a faint sweetish taste, insoluble in water, readily soluble in alcohol and ether. It becomes solid at 21° F. It is not found pure in nature, but the animal and vegetable fatty oils consist largely of it. Also elain.
    • n olein The trade-name of the oil, fluid at common temperature, obtained by means of hydraulic pressure from the butter-like tropical fats, such as cocoauut-oil and palm-oil, especially the former. It is not chemically pure olein, but contains beside this some palmitin and some of the glycerides of the lower fatty acids, such as myristin, laurin, and caprin. In the so-called olein from cocoanut there is a large proportion of laurin and but little real olein.
