HUMAN NUTRITION

Detailed explanation-1: -Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into two glucose molecules by maltase.

Detailed explanation-2: -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: -They secrete saliva in the oral cavity which contains some enzymes like amylase, lysozyme, and lingual lipase. Amylase works on carbohydrates like starch and converts them into maltose. Lysozyme kills bacteria present in the mouth by destroying their cell walls.

Detailed explanation-4: -Ptyalin is the starch hydrolyzing enzyme secreted by salivary glands in human beings. It is also called as salivary amylase. Ptyalin secreted in the mouth brings about digestion of starch in the mouth itself.

Detailed explanation-5: -Saliva contains the enzyme, salivary amylase. This enzyme breaks the bonds between the monomeric sugar units of disaccharides, oligosaccharides, and starches. The salivary amylase breaks down amylose and amylopectin into smaller chains of glucose, called dextrins and maltose.
