Description

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.

Inhibitory neurotransmitter in spinal cord, allosteric regulator of NMDA receptors.
