A neutron diffraction study of the β-form of L-glutamic acid, C5H9NO4, has been carried out. The structure is orthorhombic: space groupP212121,a= 5·159(5),b= 17·30(2),c= 6·948(7) Å andz = 4. Least-squares refinements based on 803 reflexions led to a final conventionalR value of 0·026, and bond lengths involving hydrogen atoms have been determined with an average precision of 0·004 Å. The molecule is in the zwitterion form, and no intramolecular hydrogen bonds have been found. The hydrogen atom… Expand
Precision neutron diffraction structure determination of protein and nucleic acid components. XVII. Molecular and crystal structure of the amino acid glycine hydrochloride
The amino acid salt glycine hydrochloride, H3N+⋅CH2⋅COOH⋅Cl−, crystallizes in the space group P21/c, a=7.117(2) A, b=5.234(2) A, c=13.745(3) A, β=97.25(1) °. The crystal structure has been refinedExpand
Structure of α Form of L-Glutamic Acid. α-β Transition
An X-ray analysis of the α form of L-glutamic acid, C5H9NO4, has been carried out. The space group is P212121 with a=7.068(1), b=10.277(1), c=8.755(1) A and Z=4. The structure was solved by theExpand

The whole range of hydrogen bonds in one crystal structure: neutron diffraction and charge-density studies of N,N-dimethylbiguanidinium bis(hydrogensquarate).
TLDR
Sensitive criteria such as the Laplacian of the electron density and energy densities in the bond-critical points reveal the incipient covalent character of the shortest O-H···O bond. Expand

TLDR
The observed differences between the lengths of hydrogen bonds formed by different donor and acceptor groups in amino acids and peptides, imply differences in the energetics of their formation. Expand
Protein structure refinement: Streptomyces griseus serine protease A at 1.8 A resolution.
TLDR
The algorithm used for this refinement allows for the simultaneous restraint on bond distances and distances related to interbond angles, the coplanarity of atoms in planar groups, the conservation of chirality of asymmetric centres, non-bonded contact distances, conformational torsional angles and individual isotropic temperature factors.

Weak hydrogen bonding. Part 1. Neutron diffraction data of amino acid Cα–H suggest lengthening of the covalent C–H bond in C–H ⋯ O interactions
In C–H ⋯ O contacts observed in 16 high-precision neutron crystal-structure determinations of α-amino acids, there is good evidence for a correlation between the covalent bond length of Cα–H and theExpand

Unusual zwitterion of D,L-beta-carboxyaspartic acid: pKa and X-ray crystallographic measurements.
TLDR
An investigation of the acidic properties and molecular structure of the new natural amino acid beta-carboxyaspartic acid (Asa) is described and analysis of the pKa data indicates that the predominate zwitterion in solution results from ionization of a beta- carboxyl group. Expand
