<prompt> Test to differentiate monosaccharide from disaccharides?Benedicts testSelivinoffs testBarfoeds testRapid furfural test  <response>: Ans. c Barfoeds test; Ref. Biochemistry by Dr. Deb 7th ed., 47SUGARS Best-known tests are reduction of metallic hydroxides together with oxidation of sugar. For testing reactions due to aldehyde or ketone group of sugars : Benedict test, Tollen test, Nylander test.Disaccharides are maltose, lactose and sucrose.Sucrose is invert sugar and is non-reducing sugar.Polysaccahrides are glycogen, cellulose, starch, dextrin, and inulin.Molish testto identify carbohydrate.Benedicts testfor indentification of monosaccharide glucose and fructose.Barfoeds testdistinguishes between mono and disaccharides.Benzidine testfor pentoses.SelMnoffs testfor fructose.
