Discuss the role of pancreatic amylase
What will be an ideal response?
Like salivary amylase, pancreatic amylase contributes to carbohydrate digestion by converting dietary starches (amylose and amylopectin) into the disaccharide maltose and the branched polysaccharide a-limit dextrins. Amylase is secreted in the pancreatic juice in an active form because active amylase does not endanger the secretory cells. These cells do not contain any polysaccharides.
