In later use spec. forming the names of neutral compounds, such as glycerides, glucosides, proteins, which are thus distinguished from the names of alkaloids and other basic substances ending in -ine (cf. -ine suffix5   and see note in etymology).

Also forming the names of certain non-nitrogenous heterocyclic compounds with six-membered rings, as dioxin.In some cases, forms spelt with -ine had passed into popular use before the formalization of the nomenclature, such as dextrine, gelatine, glycerine, which are still commonly so spelt in non-scientific use. For the naming of enzymes, -in (as in pepsin, trypsin) has been displaced by -ase (see -ase suffix).See also -ein suffix, -mycin suffix, -trophin comb. form, -tropin comb. form.
