Which of the following is true about the reducing properties of sugars?

Question

Quizplus · Accepted Answer

Reducing sugars are those that can donate electrons (act as a reducing agent) due to the presence of a free anomeric carbon. Monosaccharides with a free anomeric carbon (e.g. glucose, fructose) are reducing sugars, as are some disaccharides (e.g. maltose, lactose), which have a glycosidic bond that can be hydrolyzed to release a free anomeric carbon. However, some disaccharides (e.g. sucrose) have no free anomeric carbon and are therefore nonreducing sugars. Therefore, all monosaccharides and some disaccharides are reducing sugars, making choice D the only correct option.
