n. 1 (initialism of aminomethylphosphonic acid English) 2 α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid: a specific agonist for the AMPA receptor, where it mimics the effects of the neurotransmitter glutamate. n. (w: American Military Partner Association)
There are several types of glutamatergic ion channels in the central nervous system including AMPA, kainic acid and N-methyl-D-aspartic acid (NMDA) channels. In the synapse, these receptors serve very different purposes. AMPA can be used experimentally to distinguish the activity of one receptor from the other in order to understand their differing functions. AMPA generates fast excitatory postsynaptic potentials (EPSP). AMPA activates AMPA receptors that are non-selective cationic channels allowing the passage of Na and K and therefore have an equilibrium potential near 0 mV.
AMPA is a chemical compound that is a specific agonist for the AMPA receptor.
AMPA may also refer to:
- American Military Partner Association, a U.S. LGBT advocacy and support group
- Aminomethylphosphonic acid, a degradation product of glyphosate
