Glycine acts on receptors which bring out an enhanced chloride conductance. It shows highest concentrations in the spinal cord as compared to elsewhere in the brain. However, it interacts with and allostericaly activates the excitatory receptor N
-methyl-D-aspartate (NMDA), thus, resulting in excitatory transmission in brain.
Glycine comprises a single carbon molecule, that is attached to the amino and a carboxyl group.
Glycine hydrochloride (Gly·HCl) is capable of liquifying native chitosan and also helps in the preparation of regenerated chitosan membrane.
It can serve as an osmoprotectant. Glycine can act as a flexible link in proteins and can also allow the formation of helices.
Free glycine may have a protecting role in tissues against ischemia, hypoxia and reperfusion.
Inhibitory neurotransmitter in spinal cord, allosteric regulator of NMDA receptors.
