Amylase

Amylase is an enzyme which acts on starch, glycogen and other polysaccharides. It breaks up starch into it glucose and maltase. In humans there are two types of amylase, pancreatic amylase ( which is secreted in the pancreas) and salivary amylase. 

Amylase works by cleaving the 1,4-glycosidic bonds between 2 glucose molecules in the starch molecules, catalysing the hydrolysis reaction.
