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.

Wondering if someone can check this (DNA related)

1, Name the monomer of which DNA is made: Nucleotide 2. In which part of the DNA monomer will the heavy isotope 15N from e. coli be found: The base 2b. Given that 15% of the bases in a piece of DNA are thymine, calculate the percentage ...

Re: What is a mer? Measure of DNA

A polymer has many subunits. An oligomer has a few subunits. A monomer has only one. A number in front of the suffix "mer" indicates a specified number of subunits. When applied to DNA, this specifies the number of bases in the molecules. For ...

Citrate synthase stock calculation

... is wrong.please help as im really at the end of my tether!! my stock soln of CS 7.17mg/ml MW of CS 85,000(although some seem to work with monomer value of 42,500) protocol calls for me to make a 65uM stock of CS So in order to do this i took monomer as MW and; 42,500g= 1000000uM x= 65uM ...

Re: What is a monomer?

I don't disagree with you MrMistery. I call lipids "problematic" in that sense. Some, as you say, are obvious polymers. Others are clearly made up of identifiable "monomeric" subunits which, in the case of the isoprenoids, for example, are even formed by repeated condensation rea...
