Salivary amylase is an enzyme, and like almost all enzymes, high temperature will denature it. The higher the temperature, the more kinetic energy molecules will have. At a certain point, all that movement disrupts the secondary, tertiary, and quaternary structure of the enzyme. If the active site is no longer in the proper shape, it cannot attach to its substrate (amylose) and aid in its hydrolysis. Therefore, boiled salivary amylase will not hydrolyze amylose into disaccharides.

What enzyme does saliva produce?
The enzyme amylase (for breaking down starch) is produced by the salivary glands along with water and mucus
How does Alcohol inhibit salivary amylase?
Alcohol when ingested dehydrates the body. The body will try an conserve water which will allow for less saliva production.
How do you know that a chemical change is happening to the rice you are eating while it is still in your mouth?
In Biology, Rice is made up of starch. Starch is a polysaccharide which is insoluble in water and does not taste sweet. However, the salivary glands secret saliva which contains salivary amylase. The salivary amylase catalyze the digestion of starch into maltose. A chemical reaction takes place as the structure of starch is changed and new substances are produced. Maltose is a disaccharide and is soluble in water. It tastes sweet. The change in taste suggests that a chemical reaction takes place to the rice while it is in our mouth.
What 2 factors affect the boiling point of water?
Pressure & Temperature :) Apex
Why do foods require longer microwave cooking time at higher atitudes?
The boiling point of water goes down at higher altitudes, and so foods take longer to cook (because the temperature of the food doesn't usually exceed the boiling point of water).See the Related Questions about how elevation effects the boiling point of water.
Is salivary amylase water soluble?
no until water is heated.
What is produced in the salivary glands?
I really like mikaela she is a beautiful person and not so selfish and funny.
Which digestive enzyme is produced by salivary glands and what does it do?
Amylase is produced in the salivary glands and it hydrolyses (breaks down with the addition of water) starch into maltose.

How do you overcome the disadvantages of starch indicator?
All the alpha amylase molecules should rupture . Boil water and then add to the boiling water required starch. Make sure that the starch is alpha and not beta amylase. Use freshly prepared starch solution for iodometric titrations. --unnikrishnan
How do the salivary glands work in digestion?
The salivary gland produces an important digestive enzyme, called amylase, that helps to break down starches and liquefy the food in the chewing phase of digestion. Once swallowed, the food is exposed to more enzymes and processes that complete the digestion as it travels through the various areas of the digestive tract.
What is your understanding of effects of pressure changes on the boiling point of a liquid?
The effects of changing pressure on the boiling point of a liquid is that the water becomes temperature becomes higher. The boiling point will continue to rise depending on the amount of pressure applied.
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.
What is a list of the components of saliva and indicate their functions?
water- reactant for hydrolysis and to moisten food mucous- provides lubrication throughout oral cavity salivary amylase- converts starch to maltose antibacterial compounds
Explain how food gets boken done in the mouth?
Food gets broken down by these process:Motility- The tongue moves bolus around in the mouth with some help from he teeth.Secretion- The sublingual, submandibual and parotid gland secrete a mixture of water and the enzyme salivary amylase into the oral cavity.Digestion- Digestion begins in the mouth with salivary amylase. It will digest carbohydrates from ling polymers into shorter polymers. The action of chewing rips food apart and increase its surface area for interaction with enzymes
