Protéin téh lolobana ngandung saeutik glisin, iwal [[kolagén]] nu ampir sapertiluna diwangun ku glisin.

 

Glisin téh [[neurotransmitter]] inhibitor dina [[sistim saraf puseur]], utamana dina [[sungsum tulang tonggong]]. Nalika reséptor glisin diaktipkeun, Cl^- asup ka neuron ngaliwatan reséptor ionotropik, ngabalukarkeun ''[[Inhibitory postsynaptic potential]]'' (IPSP). Antagonis pikeun reséptor ionotropik ieu di antarana [[strihnin]], nu [[LD50]]-na 7.930 mg/kg pikeun beurit (oral){{fact}} sarta ilaharna ngabalukarkeun paéh alatan [[hiperéksitabilitas]]. <!--Glisin téh [[ko-agonis]] nu perlu pikeun marengan [[glutamat|Glu]] dina sistim saraf puseur. In contrast to the inhibitory role of glycine in the spinal cord, this behaviour is facilitated at the ([[NMDA]]) glutaminergic receptors which are excitatory.

 

Should any glycine claim be substantiated, it does not prove that life exists outside the [[Earth]], but certainly makes that possibility more plausible by showing that amino acids can be formed in the interstellar medium. The finding would also indirectly support the idea of [[panspermia]], the theory that life was brought to Earth from space.-->
