Coined/History
In 1826 Tiedemann and Gmelin observed that the stomachs of geese fed solely on a starch diet contained sugar. This notion helped Leuchs in 1831 to discover the amylase of saliva. Berzelius named the enzyme ?ptyalin? in 1840. In 1833 Payen and Persoz performed an ethanol precipitation and isolated a white, watr soluble substance from germinating barley which named ?diastase?. Diastase was later renamed amylase.
Definition
Amylase is the enzyme that catalyses the break down of starch into sugars. Specific amylase proteins are designated by different Greek letters eg a-amylase is for the breakdown of large alpha-linked polysaccharides, such as starch and glycogen.
