Polymorphism ofN-(1-benzotriazolylcarbonyl)-glycine

Polymorphism in the Crystallization of Glycine

Glycine crystallizes in more than three different polymorphic forms, α, β and γ. The form α and form γ have been prepared by recrystallization and quench-cooling method, respectively. The physicochemical properties of αand γ-forms of glycine were investigated. Techniques used to study the polymorphs include X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), differential sc...

Glycine–phthalic acid (1/1)

In the title compound, C2H5NO2·C8H6O4, the glycine mol-ecule exists as a zwitterion (2-aza-niumyl-ethano-ate) with a positively charged amino group and a negatively charged carboxyl-ate group. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the components into layers parallel to the ab plane. The central part of each layer is composed of hydrogen-bonded glycine zwitterions, while phthalic a...

On the reliability ofN-body simulations

The general consensus in the N-body community is that statistical results of an ensemble of collisional N-body simulations are accurate, even though individual simulations are not. A way to test this hypothesis is to make a direct comparison of an ensemble of solutions obtained by conventional methods with an ensemble of true solutions. In order to make this possible, we wrote an N-body code ca...

Magnetic Control of Polymorphism of Glycine Crystal by LLIP Method

Genetic Polymorphism in Human Glycine-rich Beta-glycoprotein

Extensive polymorphism of glycine-rich beta-glycoprotein (GBG) was found in human sera. In all instances, GBG consisted of at least five components on electrophoresis. Patterns were such that they provided evidence for four alleles (at a locus designated Gb) which were expressed as autosomal codominant traits. Gb(S) and Gb(F) were found in all populations but with different frequencies, Gb(F1) ...
