Monomers and Polymers are part of the Organic Molecules, some examples of Monomers are the monosaccharide, amino acids, fatty acid, glycerol and nucleotide. On the other hand some examples of the Polymers are, the polysaccharide, polypeptide, lipids and nucleic acids.
Lipids exist as many different classes that vary in structure and hence do not contain a common monomer
Nuclecic acids contain carbon, hydrogen, oxygen nitrogen and phosphorus.
