A colorless, odorless, tasteless solid ester of glycerol and stearic acid, C57H110O6, found in most animal and vegetable fats and used in the manufacture of soaps, candles, and adhesives and for textile sizing. Also called stearin .
OH): The process of saponification may be viewed as the gradual progressive transformation of tristearin, or some analogously constituted substance, into distearin, monostearin and glycerin, or as the similar transformation of a substance analogous to distearin or to monostearin into glycerin.
It is noticeable that with few exceptions the fatty and oily matters occurring in nature are substances analogous to tristearin, i.e.
Amongst these glycerides may be mentioned the following: Tristearin - C 3 H 5 (O C1 8 H350)3.
Some other glycerides isolated from natural sources are analogous in composition to tristearin, but with this difference, that the three radicals which replace hydrogen in glycerin are not all identical; thus kephalin, myelin and lecithin are glycerides in which two hydrogens are replaced by fatty acid radicals, and the third by a complex phosphoric acid derivative.
A fat consisting of the glyceride of one fatty acid only, such as stearin or tristearin, C3H5(O C1811350)3, the glycerin ester of stearic acid, C17H35 C02H.
