The monsaccharide glucose is best described by which one of the following statements?

Two monosaccharide units are linked by a glycosidic bond or yield 2 monosaccharide units on hydrolysis. Depending on their reducing property, they are divided into: Nonreducing disaccharides: The functional groups are involved in the glycosidic bond formation, hence free functional groups are not available Reducing disaccharides: Free functional groups are available. Key Concept: Glucose forms part of sucrose and is attached to fructose to form disaccharide i.e.,sucrose.
