since glutamate , glycine , and serine play a complex role in the regulation of n-methyl-d-aspartate ( nmda ) receptors , which are important in the control of normal cognitive processes , we hypothesized that the elevated levels of these amino acids might disrupt the normal functioning of nmda receptors and might be involved in the pathophysiology of schizophrenia .
