| Application: | Glycine has been used to quench unreacted aldehyde during sample (nuclei) preparation for scanning electron microscope. It has also been used for sample fixation in the process of immunolabeling. |
| Biochem/physiol Actions: | Glycine is a non-essential amino acid. Influx of calcium through the cell membrane is mediated by glycine-gated channel. Glycine participates in the synthesis of porphyrins, purine and serine. It also serves as a competitive agonist for glutamate in binding to the NMDA (N-methyl-D-aspartate) receptors. Glycine synthesis might be increased in rapidly proliferating cancer cells, due to increased demand for the amino acid. |
| Biochem/physiol Actions: | Inhibitory neurotransmitter in spinal cord, allosteric regulator of NMDA receptors. |
