Important Point:

Polymers / Monomers Many macromolecules consist of polymers A polymer is a large molecule built up from smaller building block molecules Monomers (a.k.a., subunits) are the building block molecules “The inherent differences between human siblings reflect variations in polymers, particularly DNA and proteins. Molecular differences between unrelated individuals are more extensive, and between species greater still . . . The molecular logic of life is simple but elegant: Small molecules common to all organisms are ordered into unique macromolecules . . . For each class (of compound) we will see that the macromolecules have emergent properties not found in their individual monomers.”

Polymers, Monomers, and Lipids polymer category of biomolecules monomer polysaccharide carbohydrates monosaccharides polypeptides proteins amino acids polynucleic acids nucleotides Lipid monomers are less persistent than the above monomers Consequently, lipids are less-readily described using the same polymeric terms
