-ine is a suffix used in chemistry to denote two kinds of substance. The first is a chemically basic and alkaloidal substance. It was proposed by Joseph Louis Gay-Lussac in an editorial accompanying a paper by Friedrich Sertürner describing the isolation of the alkaloid "morphium", which was subsequently renamed to "morphine".[1] Examples include quinine, morphine and guanidine.[2] The second usage is to denote a hydrocarbon of the second degree of unsaturation. Examples include hexine and heptine.[2] With simple hydrocarbons, this usage is identical to the IUPAC suffix -yne.
