From there, each one has differences. First, proteins are polymers of amino acids, which are organic molecules with an acidic group (carbon/oxygen) at one end of their backbone and an amine (nitrogen) group at the other end.The side chains contain carbon and sometimes oxygen, nitrogen, or sulfur, and some of the side chains are basic.hey are similar to DNA by containing monosaccharide units, but in a polysaccharide these are usually 5 or 6-carbon units and they are strung together in chains of 10 or more sugars. They are different from proteins and DNA by not being acidic (or basic).
