Unlike glutamate, NMDA only binds to and regulates the NMDA receptor and has no effect on other glutamate receptors (such as those for AMPA and kainate).
ນອກເຫນືອຈາກ glutamate, NMDA ພຽງແຕ່ເຊື່ອມຕໍ່ກັບແລະຄວບຄຸມຕົວ receptor NMDA ແລະບໍ່ມີຜົນກະທົບຕໍ່ຜູ້ຮັບສານ glutamate ອື່ນໆ (ເຊັ່ນວ່າສໍາລັບ AMPA ແລະ kainate).
