Hello students here the question is about the digestion.
00:03
So there are different questions we have to answer the questions one by one.
00:09
First is biuret reagent.
00:15
Biuret reagent is used to test for the presence of proteins.
00:30
The colorimetric reagent that will give a positive result when tested on meat is neanhydrin.
00:41
The question is that which colorimetric reagent will give a positive result when tested on meat.
00:47
Number 14 that maltose will or will not give a positive result with benedict after digestion.
00:56
So maltose will not give a benedict result because benedict solution after digestion because it is a disaccharide composed of two glucose molecules joined by alpha 4 glycosidic bonds and benedict solution is a test for reducing sugar and maltose does not have a free aldehyde or cation group.
01:12
Maltose will not give positive result because maltose that don't have any free aldehyde or cation group that can react with the reagent.
01:36
So benedict solution is a test for reducing sugar and maltose does not have a free aldehyde or cation group instead it needs to be a hydrolyzed into its constituent glucose molecule before it can give a positive result.
01:47
So maltose will not give a positive result along with the in presence of the benedict solution.
01:53
So benedict solution is the only colorimetric test that is an indication of the concentration of the product.
01:58
So maximal positive result color so the color is that is brick red color...
