Ab initio Molecular Dynamics Study of Glycine Intramolecular Proton Transfer in Water [PDF]
, 2005 We use ab initio molecular dynamics simulations to quantify structural and thermodynamic properties of a model proton transfer reaction that converts a neutral glycine molecule, stable in the gas phase, to the zwitterion that predominates in aqueous solution.

Proceedings of the National Academy of Sciences of the United States of America, 2017 Significance Enzymes of the folate cycle are among the most consistently overexpressed proteins in cancer. Whereas multiple clinical agents inhibit thymidylate synthase, no current drugs target the incorporation of one-carbon into folates via serine ...

Experimental Biology and Medicine, 1951 SummaryThe metabolism of glycine in mice has been studied after a single injection of glycine-2-C14 by following the specific activity of the uncombined glycine in plasma, liver and skeletal muscle, as well as the specific activity of the respiratory CO2.

Sci, 2021 Glycine in its neutral form can exist in the gas phase while its zwitterion form is more stable in water solution, but how many waters are actually necessary to stabilize the zwitterionic structure in the gas phase?

Meteoritic Proteins with Glycine, Iron and Lithium [PDF]
arXiv, 2021 We report that polymer amide [1] with a protein backbone of mainly glycine units and iron is present in the CV3 meteorites Acfer 086, Allende and KABA. The evidence for this is from particles of these meteorites after Folch extraction being analyzed by MALDI mass spectrometry and from the 3D physical structures that form in the various Folch solvent ...

A Search for Propylene Oxide and Glycine in Sagittarius B2 (LMH) and Orion [PDF]
Mon.Not.Roy.Astron.Soc.376:1201-1210,2007, 2007 We have used the Mopra Telescope to search for glycine and the simple chiral molecule propylene oxide in the Sgr B2 (LMH) and Orion KL, in the 3-mm band. We have not detected either species, but have been able to put sensitive upper limits on the abundances of both molecules. The 3-sigma upper limits derived for glycine conformer I are 3.7 x 10^{14} cm^

Detection of simplest amino acid glycine in the atmosphere of Venus [PDF]
arXiv, 2020 Amino acids are considered to be prime ingredients in chemistry, leading to life. Glycine is the simplest amino acid and most commonly found in animal proteins. It is a glucogenic and non-essential amino acid that is produced naturally by living bodies and plays a key role in the creation of several other important bio-compounds and proteins. We report

Detection of New Methylamine (CH$_3$NH$_2$) Sources: Candidates for Future Glycine Surveys [PDF]
Publications of the Astronomical Society of Japan, 2019, Volume
71, Issue 4, id.86, 2017 It has been a long-standing problem to detect interstellar glycine (NH$_2$CH$_2$COOH), the simplest amino acid, in studying a possible relation between the Universe and origin of life. In the last about 40 years all surveys of glycine failed, and it would be an alternative strategy to search for precursor(s) to glycine. Such studies of precursors would
