PTYALIN

Ptyalin, also known as salivary amylase, is the primary enzyme in saliva and is useful for the digestion of carbohydrates.

Its main function is to begin the chemical digestion of starches by breaking them down into simpler sugars, primarily maltose and dextrin.

Digestion Process: Ptyalin starts working in the mouth as food is chewed and mixed with saliva. It specifically targets the alpha-1,4 glycosidic bonds within the large starch molecules.

Optimal Environment: The enzyme functions best in the slightly acidic to neutral pH of the mouth (around 6.7).

Activity in the Stomach: The action of ptyalin continues as the food travels to the stomach, until it is mixed with highly acidic stomach secretions (pH 1.5 to 3.5), which inactivate the enzyme.

While only about 30% of starch digestion occurs in the mouth, this initial step is crucial as it reduces the workload for pancreatic amylase, which continues the breakdown process in the small intestine.

Lingual lepase and Amylase are the enzymes in Ptylin who can control diabetes.
