Biogenic Amines

The biogenic amines are small charged molecules that are synthesized from amino acids and contain an amino group (R–NH2). The most common biogenic amines are dopamine, norepinephrine, serotonin, and histamine. Epinephrine, another biogenic amine, is not a common neurotransmitter in the central nervous system but is the major hormone secreted by the adrenal medulla. Norepinephrine is an important neurotransmitter in both the central and peripheral components of the nervous system.
