Mouth
Digestion of starch begins in the mouth with the chewing of food (mastication) and the production of amylases immediately breaking down certain starches. Since the smaller sugars that come from amylase action on starch are sweeter tasting, if you hold a cracker in your mouth and swish saliva around it, you may notice the appearance of a sweeter taste.

Stomach
The lining of the stomach produces hydrochloric acid (HCl). This acidic environment is critical for helping eliminate unwanted bacteria as well as initiating the digestion of proteins. The stomach lining also secretes the enzyme pepsinogen, which is present in the stomach much of the time but is inactive until the acid is present, when it becomes activated as pepsin. Pepsin acts to start the digestion of proteins.

Small intestine
The small intestine is specifically designed to maximize the digestion and absorption process. The majority of carbohydrate digestion occurs in the small intestine. It is here that disaccharides (sugars composed of two monosaccharides) like sucrose, maltose, and lactose are broken down into monosaccharides, which are then absorbed directly into the cells that form the intestinal lining. Starches also get special treatment in the small intestine because the pancreas sends amylase enzymes into the small intestine to carry out the breakdown of certain starches.
