Heterocyclic amines, also sometimes referred to as HCAs, are chemical compounds containing at least one heterocyclic ring, which by definition has atoms of at least two different elements, as well as at least one amine (nitrogen-containing) group.

Heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs) are chemicals formed when muscle meat, including beef, pork, fish, or poultry, is cooked using high-temperature methods, such as pan frying or grilling directly over an open flame (1).

Heterocyclic amines (HCAs) are the carcinogenic and mutagenic chemicals formed from cooking muscle meats such as beef, pork, fowl, and fish. HCAs form when amino acids and creatine react at high cooking temperatures and are formed in greater quantities when …

As noted in Section 15.5 in connection with a discussion of aromaticity, a cyclic organic compound that contains atoms of two or more elements in its ring is a called a heterocycle. Heterocyclic amines are particularly common, and many have important biological properties.

Heterocyclic amines are particularly common, and many have important biological properties. Pyridoxal phosphate, a coenzyme; sildenafil (Viagra), a well-known pharmaceutical; and heme, the oxygen carrier in blood, are a few examples.

Heterocyclic amines appear to be formed by a Maillard reaction between creatine or creatinine, an amino acid, and a sugar such as glucose or fructose. The Maillard reaction is responsible for browning, which provides the improved appearance, flavoring, and aroma of heated foods.
