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 ...
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.

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).
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 generic phase diagram with unspecified axes; the invariant point is marked in red, metastable extensions labeled in blue, relevant reactions noted on stable ends of univariant lines. This rule is geometrically sound in the construction of phase diagrams since for every metastable reaction, there must be a phase that is relatively stable. This ...
Dimers of carboxylic acids are often found in the vapour phase. Anhydrous carboxylic acids form dimers by hydrogen bonding of the acidic hydrogen and the carbonyl oxygen. For example, acetic acid forms a dimer in the gas phase, where the monomer units are held together by hydrogen bonds. [3] Many OH-containing molecules form dimers, e.g. the ...
