What makes the digestion of carbohydrates, which paused in the stomach, resume in the duodenum?

Accepted Answer

The salivary enzymes which began digestion of the carbohydrate (generally named hydrolases but often amylase which catalyses the digestion of starch) is denatured in the stomach causing carbohydrate chemical digestion to cease. It resumes in the duodenum (start of the small intestine) due to brush border enzymes which are found on the microvilli of the small intestine and help to complete digestion.
