The answer is monosacchrides and small intestines
Carbohydrates, which include sugars and starches, amylase enzymes in the mouth and small intestines. In the small intestines, other enzymes that breakdown sugars include lactase, sucrase, and maltase. The carbohydrates are broken down into their purest form before absorption.
These elementary forms include sucrose, fructose, and lactose which are easily absorbed in the ileum of the intestine.
