Carbohydrates and lipids — practice question

The diagrams illustrate brief segments of several common polysaccharides and modified polysaccharides. The polysaccharides may be described as follows: F is made up of $\beta$-glucose monomers with $1,4$ glycosidic bonds; G is made up of $\alpha$-glucose monomers with $1,4$ glycosidic bonds; H is made up of N-acetylglucosamine monomers with $\beta$-$1,4$ glycosidic bonds. Which row correctly links the numbered diagrams with the descriptions of the polysaccharides?

  • AF: 2; G: 1; H: 3
  • BF: 2; G: 3; H: 1
  • CF: 3; G: 1; H: 2
  • DF: 3; G: 2; H: 1
