What type of reaction does amylase catalyze

Mechanical digestion includes:. Chemical digestion involves enzymes. These are proteins that function as biological catalysts. Enzymes can break down nutrients into small, soluble molecules that can be absorbed. For example, amylase causes the breakdown of starch into simple sugars. Digestive enzymes Digestion is the breakdown of large, insoluble food molecules into small, water-soluble molecules using mechanical and chemical processes.

The covalent glycosyl intermediate undergoes general base catalysed hydrolysis via attack of nucleophilic water at the anomeric centre, again catalysed by Glu and Asp These residues also form hydrogen bonds to the molecule.

This leads to a oxocarbenium ion-like transition state, which forms the deglycosylated product. Reference Protein and Structure. Sequence P 3. Click To Show Structure. Show Active Center.
