Biological polymers have directionality and structural polarity. Polymers only form by certain connections, and these connections give biological polymers a certain order. The order and direction in which these polymers are arranged provides information to other parts of the cell.
All biological polymers can be informational macromolecules. Many polysaccharides are vital signaling molecules on the surface of cells.
Polysaccharides are often composed of repeating units of only one or two monomers. These repeating polysaccharides are not good informational molecules because single repeating units do not have any diversity.
The polysaccharides that are used as signaling molecules are often found on the cell surface. These polysaccharides do not contain repeating units and often contain many different monosaccharides. Branches increase the informational complexity of these surface polysaccharides.
