Monomer o The reaction that forms a polymer from monomers is a polymerization reaction. o Most biological polymerization reactions are condensation reactions also called a dehydration synthesis reaction (see fig 5.2). Condensation reactions (a.k.a. dehydration synthesis reaction ) Hydrolysis o Diversity in polymers comes from the variation in the arrangement of the monomers.
