Used in neuroscience research to study the function of NMDA receptors, which play a critical role in learning and memory. It acts as a selective agonist, helping to understand receptor behavior and synaptic plasticity. Also explored in developing treatments for neurological disorders like Alzheimer’s and schizophrenia due to its potential to modulate glutamate signaling. Additionally, it serves as a tool in biochemical studies to investigate amino acid metabolism and enzyme specificity.
