In glucose polymers such as starch and starch-derivatives like glucose syrup, maltodextrin and dextrin the macromolecule begins with a reducing sugar, a free aldehyde. When starch has been partially hydrolyzed the chains have been split and hence it contains more reducing sugars per gram.

What type of sugar is dextrin?

Dextrin is an example of a carbohydrate. Dextrins are carbohydrates produced from hydrolyzing starch or glycogen. It is comprised of D-glucose units that are linked by α-(1→4) or α-(1→6) glycosidic bonds. Dextrins are naturally-occurring.

What are reducing sugars give examples?

A reducing sugar is any sugar that is capable for acting as a reducing agent because it has a free aldehyde group or a free ketone group . All monosccharides are reducing sugar. For example : glucose, fructose, robose and xylose.

Galactose, glucose, and fructose are all reducing sugars and also common dietary monosaccharides. -Disaccharides are formed from two monosaccharides and may be classified as either reducing or nonreducing. The glycosidic bonds are present in the nonreducing disaccharides like sucrose and trehalose.
