N-(2-Chloroacetyl)glycine
The title compound, C4H6ClNO3, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In each mol-ecule, there are N-H⋯O and N-H⋯Cl hydrogen bonds. Both mol-ecules are relatively planar, with the mean plane of the acetamide [N-C(=O)C] group being inclined to the mean plane of the acetate group [C-C(=O)O] by 9.23 (13)° in mol-ecule A and 6.23 (12)° in mol-ecule B. In the ...
متن کاملN-[(2S)-2-Chloropropanoyl]glycine
The title compound, C(5)H(8)ClNO(3), was prepared by the nucleophilic substitution reaction of (2S)-2-chloro-propanoyl chloride with glycine. The acetate group forms a dihedral angle of 84.6 (1)° with the mean plane of the C-NH-C=O fragment. In the crystal, the molecules are linked by N-H⋯O and O-H⋯O hydrogen bonds, generating a three-dimensional network, which consolidates the crystal packing.
متن کاملSpectrophotometric Determination of N-Acetyl-L-Cysteine and N-(2-Mercaptopropionyl)-Glycine in Pharmaceutical Preparations
A simple spectrophotometric method for the determination of N-acetyl-L-cysteine (NAC) and N-(2-mercaptopropionyl)glycine (MPG) in pharmaceutical preparations was developed, validated, and used. The proposed equilibrium method is based on a coupled two-step redox and complexation reaction. In the first step, Fe(III) is reduced to Fe(II) by NAC or MPG. Subsequently, Fe(II) is complexed with 2,4,6...
متن کاملMETABOLISM OF GLYCINE-l-C’* AND GLYCINE-2-C’* IN RAT BRAIN HOMOGENATES* BY LEMUEL
In 1932, Quastel and Wheatley (1) measured oxygen consumption in chopped brain tissue to which various metabolites had been added. Glutamic acid was oxidized at a relatively slow rate. According to Krebs (2), who repeated and extended these studies, L-glutamic acid was the only amino acid which was capable of maintaining the respiration of slices of brain or retina. This observation was confirm...
متن کاملGlycine–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...
