WebThe hydrolysis of esters in the presence of alkalies such as potassium hydroxide (lye) or sodium—a reaction called saponification —is utilized in the preparation of soaps from fats and oils and is also used for the quantitative estimation of esters. WebEnzymatic hydrolysis, a process in digestion in which macromolecules are split from food by the enzymatic addition of water, has been used for sample pretreatment in mercury speciation analysis. The advantage of enzymolysis is that enzymes act only on specific chemical bonds, thus chemical forms of mercury species are not likely to be altered. spherion bristol va
