Name three neurotransmitters and their functions.
- 1 decade agoFavorite Answer
Around ten "small-molecule neurotransmitters" are known:
Monoamines (epinephrine (E), norepinephrine (NE), dopamine (DA), serotonin (5-HT) and melatonin)
Three or four amino acids, depending on exact definition used: (primarily glutamic acid, gamma aminobutyric acid (GABA), aspartic acid & glycine)
Purines, (Adenosine, ATP, GTP and their derivatives)
Fatty acids are also receiving attention as the potential endogenous cannabinoid.
Over 50 neuroactive peptides (vasopressin, somatostatin, neurotensin, etc.) have been found, among them hormones such as Luteinizing hormone (LH) or insulin that have specific local actions in addition to their long-range signalling properties.
Single ions, such as synaptically released zinc, are also considered neurotransmitters by some.
Gaseous, including nitric oxide (NO) and carbon monoxide (CO)
The major "workhorse" neurotransmitters of the brain are glutamic acid and GABA.Source(s): Wikipedia
