Amylase is an enzyme that breaks down polysaccharides like starch into its constituent monosaccharides like glucose. This enzyme works best in environments like the mouth and small intestine where the pH is about 8. Amylase is secreted by your salivary glands for starch digestion in your mouth and by the pancreas for starch digestion in your small intestine. Amylase does not work in low pH environments and I think may be destroyed if the pH is low enough. This means amylase does not function and may even be destroyed in your stomach.
There is little or no digestion of starch in the stomach because the stomach contains gastric acid, which digests proteins. This acid is unable to break down starch chemically, The starch is broken down when it enters the small intestine because the secretions, such as pancreatic amylase, in the small intestine are able to break it down.
Found in my physiology book.
1.the epithelial cells are covered by a blanket of alkaline mucus and are not directly exposed to chyme.
2.the epithelial cells lack the specialized transport mechanisms found in the cell lining of the small intestine.
3.the gastic lining is impermeable to water.
4.digestion has not proceeded to completion by the time chyme leaves the stomach.
It depends on what is meant by "little digestion in the stomach".
What comes to mind is an ineffiencent ability of the stomach to digest and absorb nutrients - often called malabsorption. Many serious illnesses are linked to malabsorption. An inflamed ileum (such as with various types of Crohn's disease) can interfere with the absorption of vitamin B12 and bile salts. Any inflammation along the length of the small intestine will seriously impair the absorption of all food.
Because of the acidic conditions. Starch is digested by amylase, which is found in more alkaline conditions, such as the salivary gland, pancreas and small intestine.
The high acid content of the stomach inhibits the enzyme activity, so carbohydrate digestion is suspended in the stomach.
It is. Starch actually begins to digest in the mouth (see: amylase)
Starch turns into sugar while being digested inside your stomach.
Starch is sugar. Sugar digestion occurs in the stomach with the epigastric juices. Fats are digested in the Small Intestine.
Starch is digested by ptyalin.
Starch (carbohydrates) is broken down (digested) to maltose by salivary amylase.
rectum
No parts of a hamburger is digested in the mouth. All food is digested in the stomach. ------------------------------------------------------------------ Not true. Saliva contains enzymes that break down starch (carbohydrates) into sugars (that is why bread begins to taste sweet when chewed. Therefore the hamburger bun will start to be digested in the mouth.
Protein is digested in the stomach and small intestine.
Starch! We have amylases to digest them!!
Most of the food is digested in your stomach, where the stomach muscles contract to squeeze the food into a thick, runny liquid.
Amylase enzymes.
No, as it's digested starch turns into sugar, but they are different foods.
Forage matter that is either digested or being digested, depending on which stomach chamber you are referring to.
