Monomer - Molecular Weight

Molecular Weight

The lower molecular weight compounds built from monomers are also referred to as dimers, trimers, tetramers, pentamers, octamers, 20-mers, etc. if they have 2, 3, 4, 5, 8, or 20 monomer units, respectively. Any number of these monomer units may be indicated by the appropriate Greek prefix; e.g. a decamer is formed from 10 monomers. Larger numbers are often stated in English or numbers instead of Greek. Molecules made of a small number of monomer units, up to a few dozen, are called oligomers.
