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.
