Heterocyclic Amines (HCA)
From WaiWiki
Heterocyclic amines (HCAs) contain at least one heterocyclic ring (containing atoms of at least 2 different elements) and one amine group, attached to the heterocyclic ring. Some HCA are harmless, or even beneficial(eg vitamin B3 and B6), whereas others, created by cooking or burning, may cause cancer.
