Digestion 's primary goal to break these complex consuules into monosaccharides - mainty glucose - so they can bee absorbed into there blood faud for energy.

Gastric Phase: Acid Supresses Amylase

Once swallowed, the food bolus enters the stomach. The stomach 's highly acute environment (pH 1.5- 3.5) denatures slivary amylase, halting carbohydrante digestion. However, the stomach continues mechanical churning, mixing the bolus with gagric juices to form a semi- liquid substance called chyme. Some acid hydrolysis of carbohydhates may occur, but the bulk of carhydatate digestion is delayed until the smalheeeeine.

Absorption of Glucose into the Bloodstream

After carbohydrantes are broken down into monosaccharides, absorption events primarily in thee duodenum and jejunum. Glucose and galaktose are absorbed via activee transport, while fructose uses facilivate difusion. Thii selective absorption ensures that glucose, the body 's most critial fuel, enters the ciration efficiently.
