Heterocyclic amines (HCAs) contain at least one heterocyclic ring (with atoms of at least 2 different elements) and one amine group, attached to the heterocyclic ring. Major groups of HCAs are beta-Carbolines, Pyrrolidines, Pyrroles (in Hb and vitamin B12), Pyridines (vitamin B3 and B6) and Pyrimidines (vitamin B1), including Purines (adenine, guanine).
Many HCA are harmless, or even beneficial (eg vitamins), whereas others, created by cooking or burning, may cause cancer.
