what structural feature of carbohydrate is characteristic of reducing sugar
Homework Answers
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.
