What is Macromolecule?
A '''macromolecule''' is a [[molecule]] with a large number of [[atom]]s. The word is usually used only when describing [[polymer]]s, molecules which are made up of smaller molecules called [[monomer]]s. All [[Organic chemistry|organic]] monomers are based on [[carbon]], usually with [[hydrogen]], [[oxygen]] and [[nitrogen]]. There are [[Inorganic chemistry|inorganic]] macromolecules based on other monomers. ==Examples== * [[Protein]]s, composed of [[amino acids]]. * [[Nucleic acid]]s. ** [[DNA]], composed of [[nucleotide]]s. ** [[RNA]], similarly composed, differently structured * [[Carbohydrate]]s, composed of [[monosaccharide]] [[sugar]]s. * [[Lipid]]s or [[fat]]s composed of [[fatty acids]] and [[triglycerides]]. * [[Nylon]], composed of [[polyamide]]s. * [[Polythiazyl]], composed of polymeric [[sulphur]] nitride (SN)<sub>x</sub>. {{chem-stub}} [[Category:Macromolecules| ]]
