For the receptor to open, glutamate and either glycine or d-serine must bind to it. In fact, d-serine is a more potent agonist at the glycine site on the nmdar than glycine itself. D-serine was only thought to exist in bacteria until relatively recently; it was the second d amino acid discovered to naturally exist in humans, present as a signalling molecule in the brain, soon after the discovery of d-aspartate.Name d-serineitems specifications resultsappearance white crystals or crystalline powder conformsph 5.26.2 5.72specific rotation -13.5-16.0 -15.25state of solution 95.0% 98.50%ammonium(nh4) 0.02%
