Very long and large organic molecules called are made of small units called . Examples of the small units include sugars, which combine to form ; nucleotides, which form ; and amino acids, which form .
During formation of these polymers, water is released as a product for each of the linkage bonds- hence it is a dehydration process. The length of these monomer chains also determines the properties of the polymers. For examples, the longer the chains the higher the melting and boiling points. This is also how plastic of different properties are created from vinyl chloride monomers.
