The as-received D and L material exists in two different polymorphs: D-histidine is in the metastable monoclinic form, while L-histidine is in the stable orthorhombic form. For both the L and D enantiomers, recrystallization of the as-received material results in a mixture of the monoclinic and orthorhombic forms.
