Question

How starch is digested in stomach

Answer 1

Answer:

The salivary enzyme amylase begins the breakdown of food starches into maltose, a disaccharide. As the bolus of food travels through the esophagus to the stomach, no significant digestion of carbohydrates takes place.

Answer 2

Answer:

Starch digestion does not occur in the stomach

Explanation:

Digestion of starch begins in the buccal cavity by the action of the enzyme salivary amylase (optimum pH 6.8). About 30% of the starch is hydrolysed here into maltose.

When the food reaches the stomach, the highly acidic pH of the stomach inactivates salivary amylase, so no starch digestion takes place.

Further digestion of starch occurs in the small intestine, primarily with the help of pancreatic amylase.
