Inulin is a polysaccharide composed entirely of fructose units.Which test be used to identify the presence of fructose?
You will have to do a test to find out if fructose is in the product. You can do this with some test strips.
How many colours are observed in Benedicts test?
There are 4 colors that can be observed in Benedict's test. This is a test that is conducted to show if there is a presence of reduced sugars. This test is also referred to as Benedict's reagent.
What is the difference between Benedict's solution and fehling's solution?
Fehling's test uses tartaric acid, and Benedict's test uses citric acid
Why is the Benedict test not exclusive to glucose?
The Benedict test will return a positive value for any reducing sugar. It will work with fructose, for example. Benedict solution oxidizes all the reducing sugars such as glucose, galactose and fructose. This implies that a positive result of Benedict's test can be any of the reducing sugars, not necessarily glucose. It will oxidize the carbonyl (which present in all type of sugar classes). So if we get a positive result in the Benedict test, it is not necessarily glucose; it could be galactose or fructose that also a reducing sugar. So Benedict test can't be used to assure glucose.
What color does saliva turn into with the Benedict's solution?
Benedict's solution changes colors (blue to green to yellow to orange to red) in the presence of "reducing" sugars, which are not normally present in saliva. An interesting experiment, however, is testing table sugar with Benedict's solution. Table sugar is a glucose sugar joined to a fructose sugar, so they cannot react with the Benedict's solution and no color change occurs. Put table sugar in your mouth for a few moments, and then test the saliva. Now the Benedict's solution will react! (The reason: saliva has an enzyme, amylase, which breaks the glucose and fructose apart so that they can react to the Benedict's.)
Which chemical test shows the presence of an enzyme in a biological washing powder?
biurets test is the biochemical test for enzymesan enzyme is a protein and as the biochemical test for proteins is biurets,, its the same
What is Benedict's solution used for?
Benedict's solution is most commonly used for testing if sugars are present in any enzyme, or solution, that contains starch. ex. Water + Starch Then test for sugars with benedict's.
What tests for Lesch-Nyhan syndrome?
It is diagnosed by measuring the activity of the HPRT enzyme through a blood test. When the activity of the enzyme is very low it is diagnostic of Lesch-Nyhan syndrome. It can also be diagnosed by DNA testing. This is also a blood test.
What is varied when tested the effect of pH enzyme activity?
The pH is varied to effect, by its affect, this test.
What test is used to test for sugars in a food?
Benedict's test using Benedict's Solution.
In the exercise concerning trypsin function why was an enzyme assay like Benedict's or Lugol's IKI which test for the presence of a reaction product not necessary?
proteins do not contain sugar
What test is performed on an individual with symptoms of Krabbe disease?
The most specific test is done by measuring the level of GALC enzyme activity in blood cells or skin cells.
Does Benedict test indicate monosaccharides polysaccharides and disaccharides?
The Benedict test is useful for monosaccharides and disaccharides.
What type of is saccharide has no change when tested with benidicts solution?
Starch doesn't react in the Benedict test.
Why is Benedict's test unreliable?
its because Benedict's test only gives a possible test for reducing sugars (all monosaccharides, maltose and lactose).
Why is the Glucose Oxidase test a more specific test for urinary glucose that Benedict's test?
the tests are more simple and sensitive than Benedict's tes
What is used to test monosaccharides?
Benedict
