Digestion of Starch: Extended (CIE IGCSE Biology)

• Amylases are produced in the mouth and the pancreas (secreted into the duodenum)
• Amylases digest starch into smaller sugars

The digestion of starch

• Amylase is secreted into the alimentary canal in the mouth and the duodenum (from the pancreas) and digests starch to maltose (a disaccharide)
• Maltose is digested by the enzyme maltase into glucose on the membranes of the epithelium lining of the small intestine
