Monomer

Definition

noun, plural: monomers

(1) A molecule that may react chemically to another molecule of the same type to form a larger molecule, such as dimer, trimer, tetramer, polymer, etc.

(2) The simplest unit, or the repeating unit, of a polymer.


Supplement

A monomer may combine with another monomer through chemical bonds to form a larger molecule, as in a polymer.

Examples of monomers are amino acids that link together by a peptide bond forming a polypeptide or protein.


Word origin: from Greek mono "one" and meros "part".

Related forms: monomeric (adjective).

Compare: polymer.

Re: Protein structure

... the secondary structure identifies if the amino acid in question is in a region of helix/sheet etc (many are not), (3) the tertiary is the single (monomer) structure - although this relates to the gene and protein sequence, and is typically what one sees when one sees a ribbon structure picture. ...

Protein bonding(antigens)

... Structure Quaternary structure is used to describe proteins composed of multiple subunits (multiple polypeptide molecules, each called a 'monomer'). Most proteins with a molecular weight greater than 50,000 consist of two or more noncovalently-linked monomers. The arrangement of the monomers ...
