D-Serine Colorimetric Assay Kit D-form amino acids have long been known as components of bacterial cell wall peptidoglycan layers. More recent  developments in analytical technologies have demonstrated that D-amino acids are also present in mammals and  display specific and important physiological activities. Particularly high levels of D-serine levels are present in brain  tissue where D-serine functions as an important co-agonist of N-methyl-D-aspartate (NMDA) receptors (NMDR),  involved in regulating higher brain function such as memory and learning. D-serine is suggested to play a role in  neurodegeneration associated with diseases such as Alzheimer's disease (AD) and amyotrophic lateral sclerosis  (ALS). High levels of free D-serine can also be found in human urine although its significance is unclear.
 D-serine is commonly assayed by HPLC or GC following conversion of D-serine to diastereomer derivatives. Such  methods are time consuming, require expensive instrumentation, and are not suitable for processing large  numbers of samples. The D-Serine Colorimetric Assay Kit employs the D-form specific enzyme D-serine  dehydratase from Saccharomyces cerevisiae ( DsdSC ) enabling the quantitation of D-serine by  spectrophotometric measurement.
