How would benedict's solution mixed with starch and saliva react?
Benedict's solution is used to test for the presence of reducing sugars. When mixed with starch and saliva, the reaction would depend on whether the starch in the solution has been broken down by the enzyme amylase present in saliva into simpler sugars. If starch is broken down into reducing sugars like maltose or glucose, then the Benedict's solution would change color from blue to green, yellow, orange, or red, indicating a positive result for reducing sugars.
What material are required for starch test?
To test for starch, you will need iodine solution and the sample you want to test. The iodine solution will react with the starch to produce a blue-black color, confirming the presence of starch in the sample.
What does pancreatic amylase react or act on?
Amylase is the enzyme responsible for breaking down starch.
Why is the leaf discolored when testing for starch?
When testing for starch, the leaf is boiled in alcohol to remove the chlorophyll that may mask the iodine-starch color change. If the leaf turns blue-black after applying iodine, it indicates the presence of starch. If the leaf remains discolored, it suggests that starch is absent, as the iodine did not react with any starch molecules present in the leaf.
What regent would you add to starch agar plate to detect starch hydrolsis?
Iodine should be sufficent. When starch and iodine are present they react with each other and the starch turns blackish. If your bacteria hydrolise your starch then the area will be clear instead of blackish.
What happens when glucose and starch react together?
Glucose and starch do not react together chemically. However, enzymes such as amylase can break down starch into glucose through a process called hydrolysis. This allows the glucose to be used for energy production in the body.

What happens if you put a drop of iodine on a piece of paper?
If you put a drop of iodine on a piece of paper, it will react with starch on the paper turning it blue-black. This is a common test for the presence of starch.
Will corn starch react with vinegar?
no
What do pop rocks react with?
Liquid, or saliva
What substances in the bond paper does the iodine painted on the skin react?
starch starch
What happens if you add iodine to potato?
If you add iodine to a potato, the iodine will react with the starch present in the potato. This reaction will result in a color change, turning the potato a blue-black color where starch is present. This can be used as a test to detect the presence of starch in foods.
What happens when iodine is added to carrot?
The colour of the iodine will turn from yellowish brown to dark blue
Why did a solution of saliva and oats test positive with benedict's test and iodine test if the oats alone tested positive only in the iodine test and the saliva alone was negative for both?
Saliva contains the enzyme amylase which breaks down starches in oats into simple sugars like glucose, which can then react with Benedict's solution to give a positive test result. The iodine test detects the presence of starch, which is in oats but not in saliva, explaining why the combination tested positive in both tests.
What is result when silver nitrate is added to a starch?
When silver nitrate is added to starch, no reaction occurs. Silver nitrate does not react with starch molecules.
What substance on the bond paper does the iodine painted on the skin react?
starch
What parts of a leaf does not react to iodine?
The waxy cuticle and the upper epidermis of a leaf do not react to iodine because iodine cannot penetrate these barriers to reach the underlying starch-containing cells.
