To favor the existence of the free aldehyde form by suppressing ring formation.
If the sugar exist in the ring form it can not react
A Benedict's reagent is a buffered solution of copper sulphate which changes from blue to red in the presence of a reducing sugar.
No, surcose is a disaccharide without a hemiacetal group
Benedicts reagent is used to check reducing sugars , it need hat to work and gives red color when positive ,. While biuret reagent is for proteins .there is no need to use heat and gives purple , violet color when positive ..
Sucrose. Sucrose is a disaccharide therefore does not have free electrons in the sugar to react with the Benedict reagent. Glucose has free electrons therefore shows positive with the Benedict reagent.
All the compounds having free aldehyde group as reducing sugars.
No, Benedicts reagent will show positive results if the carbohydrate is a reducing sugar. You will know if it is positive if the sample will turn from blue to green then to orange when you are cooling the solution, which is the last step when you are performing the benedicts test for carbohydrates.
It tests for glucose.
Benedicts reagent tests for reducing sugars, so the question is, is raffinose a reducing sugar. Raffinose is a trisaccharide made up of glucose, fructose and galactose. It is not a reducing sugar because all of its anomeric carbons are bonded, so it will not react with benedicts reagent.
yes
the sugar glucose
The Benedict reagent is not for sodium chloride testing.
what kind of bio molecule is this when mix with a benedicts reagent and biuret reagent

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.
all reducing sugars - monosaccharides like glucose and a few non-reducing disaccharides like maltose
