Because it breaks the food up that your eating I think
Starch is a large macromolecule, so needs to be broken down into simple sugars which can be absorbed into the blood stream
The digestion of fat will begin in the small intestine, whereas the digestion of starch which begin in the mouth (the mouth contains the enzyme amylase, which helps break down starch)
In the mouth.
glucose.
yes temperature affects starch digestion, amylase work harder and better at higher temperatures
I don't think of it as an organ, but chemical digestion of starch begins in the mouth, using saliva.
In chemical Digestion, starch and fat are digested by the enzymes in saliva
The digestion of starch begins in the mouth during mastication. The ptyalin enzyme (an amylase) converts the starch to sugar .
Starch is a complex carbohydrate therefore it cannot be used and is insoluble unless it is broken down. Also the body requires glucose for important metabolic functions (respiration) to provide energy for the body, starch cannot be used for this process.
