A reducing sugar is any sugar that is capable of acting as a reducing agent because it has a free aldehyde group or a free ketone group. All monosaccharides are reducing sugars, along with some disaccharides, oligosaccharides, and polysaccharides.
So,for carbohydrates to be a reducing sugar it must have a free aldehyde or ketone group.Its is one of the most important characteristic strucutral feature of carbohydrates.
monosaccharides,Glucose and fructose are reducing sugars because they contain free aldehyde and ketone group respectively.
whereas Disaccharides,Sucrose is a non reducing sugar because it does not have free aldehyde or ketone groups.

What is a reducing sugar? What is the significance of the reducing ability of a sugar? Questions 1. What is a reducing sugar? What is the significance of the reducing ability of a sugar? 2. Draw the structure of each sugar tested and indicate the reducing potential of each sugar. Were your results in agreement with those expected?
15 points) You are given a carbohydrate to analyze. It behaves as a reducing sugar with a Tollen's test. When you exhaustively methylate it with alkaline CH3l and then hydrolyze with strong acid, you get the following in an equal molar ratio (1:1); 2,3,4,6-tetra-o-methylgalactose 2,3,6-tri-O-methylglucose You try reacting it with different glycosidases, and get the following results: a-galactosidase: No reaction B-galactosidase: produces galactose and glucose (1:1) as products a-glucosidase: No reaction B-glucosidase: No reaction . (2 point) Based upon these...
Which of the following is a chemical or structural characteristic of RNA? The RNA sugar is ribose, which has an OH group on the 2' carbon. O RNA is usually a single-stranded molecule. The bases in RNA include uracil instead of thymine. RNA molecules are generally shorter in length compared DNA macromolecules. All of the above are either a chemical or structural characteristic of RNA. Which of these sequences could form a hairpin? 5' GGGGTTTTCCCC 3' 5' AAAAAAAAAAAA 3' 5'...
