Digestion of carbohydrates:

In buccal cavity:

• Saliva secreted into the buccal cavity contains electrolytes such as Na⁺, K⁺, Cl^-,  enzymes such as salivary amylase and lysozyme.
• Hydrolytic action of salivary amylase hydrolyses the starch into maltose.

In small intestine:

• Pancreatic amylase present in the pancreatic juice hydrolyses remaining carbohydrates into disaccharides.
• Diasccharidases (enzymes present in the intestinal juice) such as maltase, sucrase, lactase breakdown disaccharides into monosaccharides such as glucose, maltose, fructose, etc.
