Pyrroles are components of larger aromatic rings, including the porphyrins of heme, the chlorins and bacteriochlorins of chlorophyll, and the corrin ring of vitamin B12.

Pyrrole has very low basicity compared to amines and other aromatic compounds like pyridine where the ring nitrogen is not connected to a hydrogen atom. This is because the lone pair of electrons of the nitrogen atom becomes delocalized in the aromatic ring.
