(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.

Stearin
Definition:
(n.) One of the constituents of animal fats and also of some vegetable fats, as the butter of cacao. It is especially characterized by its solidity, so that when present in considerable quantity it materially increases the hardness, or raises the melting point, of the fat, as in mutton tallow. Chemically, it is a compound of glyceryl with three molecules of stearic acid, and hence is technically called tristearin, or glyceryl tristearate.
Example Sentences:
(1) The dietary fats were corn oil, soybean oil, palm oil, palm olein and palm stearin.
