The carbohydrate portion of some glycoproteins may serve as a cellular recognition site. To perform this function, the oligosaccharide must have to potential to exist in a variety of forms. Which can produce a greater variety of structures: oligosaccharides composed of five different amino acid residues or oligosaccharide composed of five different monosaccharide residues?
