Neurotransmitter classification
Neurotransmitters can be classified into the following types:-
They can also be classified into excitatory and inhibitory forms.
- Small molecules
- Amino acids
- Neuroactive peptides
- Soluble gases
| Subtype | Examples |
|---|---|
| Small molecules | Acetylcholine, Dopamine, Norepinephrine, Serotonin, Histamine, Epinephrine |
| Amino acids | Gamma-aminobutyric acid (GABA), Glycine, Glutamate, Aspartate |
| Peptides | Oxytocin, Gonadotropnin-releasing hormone, Prolactin |
| Soluble gases | Nitric Oxide, Carbon Monoxide |
They can also be classified into excitatory and inhibitory forms.
| Group | Neurotransmitter | Function |
|---|---|---|
| Acetylcholine | Acetylcholine | Excitatory |
| Amines | Epinephrine | Excitatory |
| Amines | Norephinephrine | Excitatory |
| Amines | Dopamine | Excitatory and Inhibitory |
| Amines | Serotonin | Excitatory |
| Amino Acids | Glutamate | Excitatory |
| Amino Acids | Glycine | Mainly inhibitory |
| Amino Acids | g-Aminobutiric acid (GABA) | Inhibitory |
