Glycine is a required co-agonist along with glutamate for NMDA receptors. In contrast to the inhibitory role of glycine in the spinal cord, this behaviour is facilitated at the glutamatergic receptors which are excitatory. [41] The LD 50 of glycine is 7930 mg/kg in rats (oral), [42] and it usually causes death by hyperexcitability. [citation ...
The phase diagram shows, in pressure–temperature space, the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas. The curves on the phase diagram show the points where the free energy (and other derived properties) becomes non-analytic: their derivatives with respect to the coordinates (temperature and ...
A plot of typical polymer solution phase behavior including two critical points: a LCST and an UCST. The liquid–liquid critical point of a solution, which occurs at the critical solution temperature, occurs at the limit of the two-phase region of the phase diagram. In other words, it is the point at which an infinitesimal change in some ...
I've just updated the 3D images of glycine with data from the crystal structure: CrystEngComm (2008) 10, 335-343. I know that the tradition on Wikipedia is to depict amino acids as uncharged species, not zwitterions, but there is a problem: glycine only exists as a cation, a zwitterion, or an anion (except in the gas phase).

English: Glycine and serine catabolism in and out of the mitochondria. Inside the mitochondria, the glycine cleavage systems links to the serine hydroxymethyltransferase in a reversible process allowing for flux control in the cell.
In chemistry, the lever rule is a formula used to determine the mole fraction (x i) or the mass fraction (w i) of each phase of a binary equilibrium phase diagram.It can be used to determine the fraction of liquid and solid phases for a given binary composition and temperature that is between the liquidus and solidus line.
Analysis of neutron diffraction data for glycine showed that it was in the zwitterionic form in the solid state and confirmed the presence of hydrogen bonds. [5] Theoretical calculations have been used to show that zwitterions may also be present in the gas phase for some cases different from the simple carboxylic acid-to-amine transfer. [6]
