The stomach breaks down mainly proteins into smaller polypeptides. However, amylase will not break anything down in the stomach because it is denatured by the acid. Salivary amylase will break down amylose, a type of starch, but only in the few seconds of mastication. Once the bolus reaches the stomach, the salivary amylase is no longer active. Carbohydrates will be broken down again in the small intestine, where pancreatic amylase will make a return after the chyme is neutralized into a basic solution.

What is the chemical reaction used to break down carbohydrates?
Carbohydrates begin digestion in the mouth with the help of the enzyme salivary amylase this process continues in the duodenum with the help of the enzyme amylase and it finishes off in the illeum still using amylase. Carbohydrates are broken down into polysaccharides which are chains of sugar and are then broken down into monosaccharides which are simple sugars. monosaccharides are the final break own product for carbohydrates. Proteins are digested in the stomach using the enzyme pepsin. continues to the duodenum and uses the enzyme trypsin and continues then to the illeum and uses the enzyme erepsin. proteins are broken down into polypeptides after this they are broken down into dipeptides and after this are then broken down into amino acids which is the final breakdown product. fats are broken down in the duodenum and the illeum . they are broken down in both using the enzyme lipase. they are broken down into fatty acids first and then into glycerol. glycerol is the final breakdown product for fats.
What enzyme breaks down starch into sugars which are than broken down by the other three enzymes?
starch can be broken down into simple sugars by the enzyme amylase
Will amylase break down glycogen into glucose?
Yes, amylase can break down glycogen.
What enzyme breaks down food in the mouth?
The enzyme released into the mouth via salivary glands are called salivary amylase. This enzyme is what breaks down starch and starts the chemical digestion. When the bolus (chewed up food covered in saliva) enters the stomach, the pH is too low and thus the amylase denatures, and no more starch is broken down.
Why is starch not broken down at high temperatures?
The enzyme amylase is denatured by the high temp. The starch cannot be broken down
What disaccharide does the digestive enzyme amylase break down starch to?
Amylase helps the break down of starch into sugars (disaccharides). Amylase itself is not broken down. It is an enzyme and it doesn't enter into the reaction in any way. The disaccharide that is formed is sucrose, maltose or lactose.
Why does amylase work in the mouth but not the stomach?
Because of enzyme specificity, enzymes require certain temperatures and pH's to work. Now I don't think there is a temperature change, but there is most certainly a pH change as the mouth has a near neutral pH while the stomach has a more acidic pH of about 2-3.
Which organs produce the enzyme lipase needed for triglyceride digestion?
salivary amylase.
What are starch molecules broken up by?
Starch is typically broken down by the enzyme amylase pretty effectively. To check to see if the amylase is working properly, you can add the enzyme in a solution of starch and constantly check the concentrations of starch at certain intervals of time using a spectrometer.
What enzyme dissolves starch?
Amylase enzymes.
What is the name of the enzyme that digests starch?
AMYLASE
If your mouth produces amylase and your stomach is highly acidic what happens to the amylase when you swallow?
Amylase is an enzyme, which is a type of protein. Protein denatures when temperature or pH (acidity) is changed. for example, amylase will no longer digest starch if you put it in a boiling water bath for 5 minutes. in the stomach, hydrochloric acid is produced by the stomach lining to digest food. this acid will denature the amylase when the swallowed food mixed with amylase from the mouth enters the stomach.
