Study Notes
- Amino acids are the most common neurotransmitters in the central nervous system.
- Glutamate is the most prevalent excitatory neurotransmitter, while GABA is the most prevalent inhibitory neurotransmitter.
- Monoamines are another class of neurotransmitters that are slightly larger than amino acid neurotransmitters.
- Monoamines are synthesized from a single amino acid and tend to have more diffuse effects.
- There are four monoamine neurotransmitters: dopamine, epinephrine, norepinephrine, and serotonin.
- Dopamine, norepinephrine, and epinephrine are catecholamines, while serotonin is an indolamine.
- Noradrenergic neurons release norepinephrine, while adrenergic neurons release epinephrine.
- Tyrosine is converted to l-dopa, which is then converted to dopamine.
- Neurons that release norepinephrine have an extra enzyme that converts dopamine to norepinephrine.
- Serotonin is synthesized from the amino acid tryptophan.
