Editing NMDA receptor (section)

====Examples====
Some known NMDA receptor agonists include:
* [[Amino acid]]s and amino acid derivatives
** [[Aspartic acid]] (aspartate) ([[aspartic acid|<small>D</small>-aspartic acid]], [[aspartic acid|<small>L</small>-aspartic acid]]) – endogenous glutamate site agonist. The word ''N''-methyl-<small>D</small>-aspartate (NMDA) is partially derived from <small>D</small>-aspartate.
** [[Glutamic acid]] (glutamate) – endogenous glutamate site agonist
*** [[Tetrazolylglycine]] – synthetic glutamate site agonist
*** [[Homocysteic acid]] – endogenous glutamate site agonist
*** [[Ibotenic acid]] – naturally occurring glutamate site agonist found in ''[[Amanita muscaria]]''
*** [[Quinolinic acid]] (quinolinate) – endogenous glutamate site agonist
** [[Glycine]] – endogenous glycine site agonist
*** [[Alanine]] ([[alanine|<small>D</small>-alanine]], [[alanine|<small>L</small>-alanine]]) – endogenous glycine site agonist
*** [[Milacemide]] – synthetic glycine site agonist; prodrug of [[glycine]]
*** [[Sarcosine]] (monomethylglycine) – endogenous glycine site agonist
*** [[Serine]] ([[serine|<small>D</small>-serine]], [[serine|<small>L</small>-serine]]) – endogenous glycine site agonist
* [[Positive allosteric modulator]]s
** [[Cerebrosterol]] – endogenous weak positive allosteric modulator
** [[Cholesterol]] – endogenous weak positive allosteric modulator
** [[Dehydroepiandrosterone]] (DHEA) – endogenous weak positive allosteric modulator
** [[Dehydroepiandrosterone sulfate]] (DHEA-S) – endogenous weak positive allosteric modulator
** [[Nebostinel]] (neboglamine) – synthetic positive allosteric modulator of the glycine site
** [[Pregnenolone sulfate]] – endogenous weak positive allosteric modulator
* Polyamines
** [[Spermidine]] – endogenous polyamine site agonist
** [[Spermine]] – endogenous polyamine site agonist
