l-2-Nitrimino-1,3-diazepane-4-carboxylic acid monohydrate
The cyclic form of l-nitro-arginine, C(6)H(10)N(4)O(4), crystallizes with two independent mol-ecules in the asymmetric unit. According to the geometrical parameters, similar in both mol-ecules, the structure corresponds to that of l-2-nitrimino-1,3-diazepane-4-carboxylic acid; there are, however, conformational differences between the independent molecules, one of them being close to a twisted ...
متن کاملPotassium l-2-nitrimino-1,3-diazepane-4-carboxylate monohydrate
The title compound, K(+)·C(6)H(9)N(4)O(4) (-)·H(2)O, crystallizes with the K atoms located on special positions related by pseudocentres of symmetry. Each K atom is coordinated by six O-atom donors. The N and water H atoms are involved in inter- and intra-molecular N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonding. The data indicate inversion twinning.
متن کامل2-(Carboxymethylsulfanyl)pyridine-3-carboxylic acid monohydrate
The title compound, C(8)H(7)NO(4)S·H(2)O, was obtained by reaction of 2-mercaptopyridine-3-carboxylic acid with chloro-acetic acid. In the mol-ecular structure, the dihedral angle between the two least-squares planes defined by the pyridine ring and the carb-oxy group is 8.32 (9)°. The carboxy-methyl-sulfanyl group makes a torsion angle of 82.64 (12)° with the pyridine ring. An intra-molecular ...
متن کاملL-2-[(13)C]oxothiazolidine-4-carboxylic acid: a probe for precursor mobilization for glutathione synthesis.
L-2-oxothiazolidine-4-carboxylic acid (OTZ), a 5-oxoproline analog, is metabolized by 5-oxoprolinase and converted to cysteine, the rate-limiting amino acid for GSH synthesis, with the release of CO(2). [(13)C]OTZ (1.5 mg/kg) was used in 12 healthy men and women (ages 23-73 yr) to indirectly assess precursor mobilization for GSH synthesis when stores were reduced by 2 g acetaminophen. Expired b...
متن کامل2-(4-Bromobenzenesulfonamido)-2-phenylacetic acid monohydrate
In the title compound, C(14)H(12)BrNO(4)S·H(2)O, the phenyl and benzene rings are inclined at a dihedral angle of 39.5 (5)°. The crystal packing is stabilized by N-H⋯O, C-H⋯O and O-H⋯O hydrogen-bonding inter-actions.
