Which statement accurately describes the difference between homopolysaccharides and heteropolysaccharides?

Homopolysaccharides are typically branched, whereas heteropolysaccharides are linear.

Homopolysaccharides consist of one type of monomer, while heteropolysaccharides contain more than one type. (correct)

Homopolysaccharides contain multiple types of monomers, while heteropolysaccharides consist of a single type.

Homopolysaccharides have a defined molecular weight, while heteropolysaccharides do not.

What distinguishes a reducing sugar from a non-reducing sugar?

Reducing sugars can undergo oxidation, while non-reducing sugars cannot. (correct)

Non-reducing sugars can form glycosidic bonds, while reducing sugars cannot.

Non-reducing sugars contain a free aldehyde or ketone group, whereas reducing sugars do not.

Reducing sugars are soluble in alcohol, while non-reducing sugars are not.

Which of the following best explains why sucrose is considered a non-reducing sugar?

It has a glycosidic bond between two specific monosaccharides that prevents oxidation. (correct)

It contains a free aldehyde group available to reduce other compounds.

It can form a reducing agent when hydrolyzed.

It is a polysaccharide that does not involve any reducing properties.
