saponification

 [sah-pon″ĭ-fĭ-ka´shun]
conversion of an oil or fat into a soap by combination with an alkali. In chemistry, the term now denotes the hydrolysis of an ester by an alkali, resulting in the production of a free alcohol and an alkali salt of the ester acid.

sa·pon·i·fi·ca·tion

(să-pon'i-fi-kā'shŭn),
Conversion into soap, denoting the hydrolytic action of an alkali on fat, especially on triacylglycerols; in histochemistry, saponification is used to demethylate or reverse blockage of carboxylic acid groups, thus permitting basophilia to occur.
[sapo- (sapon-) + L. facio, to make]
