Detailed explanation-1: -Carbohydrates. The digestion of carbohydrates begins in the mouth. The salivary enzyme amylase begins the breakdown of food starches into maltose, a disaccharide.
Detailed explanation-2: -The chemical digestion of two groups of molecules, carbohydrates, and fats, also begins in the mouth. Carbohydrates are the sugars and starches we eat, and an enzyme called salivary amylase begins the chemical breakdown of starches as we chew our food.
Detailed explanation-3: -Salivary amylase is a glucose-polymer cleavage enzyme that is produced by the salivary glands.
