The complex carbohydrates pictured below are made by linking molecules of glucose. In all three complex carbohydrates, the subunits of glucose are bonded together differently. Because they have different structures, they most likely -

• contain different chemical elements
• form different proteins
• carry different nucleotides
• perform different functions
