The chemical properties of an amino acid are largely dictated by the nature of its variable R-group.  Non-polar amino acids are a class of amino acids in which the variable R-group is comprised of mostly hydrocarbons [1]; the amino acids cysteine and methionine also feature a sulphur atom, but (due to its similar negativity to carbon) this does not confer any polar properties to either of these amino acids [2].

The non-polar amino acids are[3]:
