Starch digestion and the end product?

Answer 1

The breaking down of starches begins in your mouth with salivary amylase.
Mouth.

Your saliva contains the enzyme known as amylase, which digests starch.

If you leave something with sugar in it on your tongue, you can taste the sweetness when the amylase starts to break it down.

Answer 2

Starch is a polysaccharide, made up of many alpha glucose molecules that are joined with glycocidic bonds through condensation.

During ingestion, the food is taken into our mouth and broken down by chewing. The chewed food is mixed with saliva that comes from the salivary glands. The saliva contains the enzyme amylase which breaks down the starch in the food into maltose using hydrolysis. The saliva also maintains a neutral pH in which the amylase enzyme works best.

The food is then swallowed and enters our stomach. The stomach is acidic so the amylase enzymes, that were used to begin breaking down the starch, are denatured which stops any further hydrolysis from occuring.

After the food has passed through the stomach, it enters the small intestine. The pancreas creates amylase to further break down the starch that wasn't broken down into maltose before it reached the stomach. This pancreatic amylase is secreted into the small intestine where it mixes with the food. Alkaline salts are made by the pancreas and small intestine wall to keep the pH at neutral. This means the amylase can work efficiently.

The intestinal walls contain muscles that push the food along the small intestine. The enzyme maltase, that breaks down the disaccharide maltose, is produced in the epithelial lining of the small intestine. The maltase then hydrolises the maltose into many alpha glucose molecules.

Answer 3

Starch digestion begins in the mouth with the enzyme amylase breaking down starch into maltose. In the small intestine, pancreatic amylase further breaks down maltose into glucose, which is the end product of starch digestion. Glucose is then absorbed into the bloodstream and used for energy by the body.

Answer 4

In the oral cavity. Saliva contains an enzyme amylase which catalyzes the break up of starchy foods.

Answer 5

primary end products; maltose, maltotriose, a-dextrins, and some glucose

Answer 6

it takes place in the mouth and small intstine. the enzyme salivary amylase breaks starch down into maltose.

Answer 7

Protein digestion begins in the stomach and ends in the small intestine.

Answer 8

in the small intestine

Answer 9

the mouth
