Amylase | Definition, Function, & Facts | Britannica
2024年10月16日 · Amylase, any member of a class of enzymes that catalyze the hydrolysis (splitting of a compound by addition of a water molecule) of starch into smaller carbohydrate molecules such as maltose. Three categories of amylases, denoted alpha, beta, and gamma, differ in the way they attack the bonds of the starch molecules.
Amylase - Wikipedia
An amylase (/ ˈ æ m ɪ l eɪ s /) is an enzyme that catalyses the hydrolysis of starch (Latin amylum) into sugars. Amylase is present in the saliva of humans and some other mammals, where it begins the chemical process of digestion.
