Alpha Amylase acts upon large polysaccharides at the alpha-1,4-glucoside bonds. The hydrolytic products have alpha configuration. The activity is present in all living organisms, however the enzymes vary remarkably even from tissue to tissue within a single species.
Source:
Amylase, alpha, from porcine pancreas.
