Question

Identify the amino acids that give rise to catecholamines, serotonin, GABA, and histamine.

Short answer

The amino acid makes neurotransmitters and hormones. The amino acids that give rise to catecholamines and serotonin are tyrosin and tryptophan. GABA and histamine are from aminobutyric acid and histidine.

Step-by-step solution

The Biogenic Amines

The three catecholamines—dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline), as well as histamine and serotonin—are the five recognized biogenic amine neurotransmitters. The characteristics of the amine neurotransmitters lay in between those of the other small-molecule neurotransmitters and those of the neuropeptides in terms of synthesis, packaging, release, and breakdown.

Physiologically active amines.  

Each of these biologically active amines is produced by the decarboxylation of its matching precursor amino acid. Tyrosine, 5-hydroxytryptamines, -aminobutyric acid, and histidine amino acids are used to make catecholamines, serotonin from 5-hydroxytryptamines, GABA from -aminobutyric acid, and histamine from histidine amino acids.
