Except for the branch points of amylopectin, the glucose monomers in starch are linked via alpha(1-4) glycosidic bonds, which, in the digestive tract of mammals, are hydrolyzed by amylases. Cellulose is the other major plant carbohydrate. It is the major constituent of plant cell walls, and more than half of the organic carbon on earth is found ... For example, caprolactone is ring-opened to produce polycaprolactone. Caprolactone and other ROP monomers are different from the monomers used in condensation polymerization in a couple of ways. First of all, ROP monomers contain only one functional group, not two. Furthermore, they don't need a complementary monomer.

When two monomers join, a hydroxyl (OH) group is removed from one monomer and a hydrogen (H) is removed from the other. This produces the water given off during a condensation reaction. Hydrolysis (hydration) reactions break down polymers in reverse of condensation; a hydroxyl (OH) group from water attaches to one monomer and hydrogen (H ...
