Because amylase, being an enzyme, is a protein, these molecules will not give a positive result in testing with Benedict's solution.
This reagent is devised for testing sugar solutions (like sucrose), which MAY be formed at the amylolytic breakdown of starch (amylose, amylopectin). This breakdown can NOT occur when boiled enzym molecules are used (because of inactivation by denaturation of the protein structures).
Once you boil the enzyme, it will be inactivated. Milk will have no effects of the enzyme.
gas + gas
It's called a 'precipitate'Example:(solution of) Ag+ + (solution of) Cl- ==> (precipitate) AgCl This is a white, cloudy suspension of tiny particles, called 'precipitate'
For a compound AB it is the result of the product [A].[B] in solution.
The result is that you have a solution, which is a homogeneous mixture, which means that the solution is uniform throughout.
Maltose. Water and Starch mixed with amylase makes maltose
yes
Turns blue black
When boiled rice is chewed, the salivary amylase of the saliva changes the starch to maltose. Thus it tasted sweet and gave a negative result with iodine.Thanks
Perhaps the iodine solution was old and gave a false negative.
Yes, it should. Benedicts test will be positive for reducing sugars, and since glucose is such a sugar, and would be a product of dextrin hydrolysis, you should get a positive result with Benedicts reagent.
Iodine test is a procedure that tells whether a certain element or the such contains starch (or sugar) in it.In this test, we add iodine solution (with, possibly, KI reagent) to a material [in your case, sugar]. If starch ispresent, a blue-black, somehow purple, color will result, changing the initial color of iodine. If starch amylase (sugar) is NOT present, the color will remain orange/yellowish.
Solution is the mixture and the result of a solute and a solvent
DNSA reagent appears yellow due to ts nitro gp.(chromophore) an alkaline solution of Dnsa is boiled with the reducing sugar to bbe estimated Orange brown coloration result which is read colorimetrically.
Solid medium
Solution.
It is the solution of the equation
