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. As the bolus of food travels through the esophagus to the stomach, no significant digestion of carbohydrates takes place.
Detailed explanation-2: -Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb. Saliva also contains an enzyme called lingual lipase, which breaks down fats.
Detailed explanation-3: -Chemical digestion in the mouth is minor but consists of salivary amylase (ptyalin, or alpha-amylase) and lingual lipase, both contained in the saliva. Salivary amylase is chemically identical to pancreatic amylase and digests starch into maltose and maltotriose, working at a pH optimum of 6.7 to 7.0.
Detailed explanation-4: -Salivary amylase is a glucose-polymer cleavage enzyme that is produced by the salivary glands.
Detailed explanation-5: -Salivary Glands It has a cleansing action on the teeth. It moistens and lubricates food during mastication and swallowing. It dissolves certain molecules so that food can be tasted. It begins the chemical digestion of starches through the action of amylase, which breaks down polysaccharides into disaccharides.
