<prompt> Reducing sugar in urine can be detected by -Benedicts testFehling solutionGlucose-oxidase testAll of the above  <response>: Ans. is d i.e., AH of the above Detection of reducing sugarso Reducing property of sugars in alkaline solution is utilized for both qualitative and quantitative determination of sugars. Reagent containing Cu ions are most commonly used. These are generally alkaline solution of cupric sulfatei Benedicts quantitative reagent CuSO4, Na2CO3, sodium citrate, potassium ferrocyanide, potassium thiocyanide can detect any reducing sugar.ii Fehling solution contains CuS04, Ruchelle Salt sodium potassium tartarate and strong alkali NaOH KOH. It is not used now.iii Glucose oxidase method : - This method i s specific for glucose. Peroxidase and oxidase enzymes are used forestimation of glucose. These enzymes are the basis of highly specific test strips used for detction of glucose in urine or blood.
