X-Ray Diffraction Studies on Some Sodium Soaps.

Characterization of some commercial soaps by X-ray diffraction.

X-ray Diffraction Studies on Crystalline Complexes

Complexes of the gene 5 protein with a variety of oligodeoxynucleotides, ranging in length from two to eight and having several different sequences, have been formed and crystallized for x-ray diffraction analysis. The crystallographic parameters of four different unit cells, all of which are based on hexagonal packing arrangements, indicate that the fundamental unit of the complex is composed ...

X-ray Diffraction Studies on Frog Muscles

1. X-ray diffraction studies of sartorius muscles of Rana pipiens were made in a new x-ray diffraction camera which permits exposures of 3 to 6 minutes. The object-film distance can be varied from 20 to 80 mm; the muscle inside the camera can be electrically stimulated while contracting isotonically or isometrically, and can be observed by a special device. After exposures up to 30 minutes (app...

X-Ray Diffraction of Some Biphenylcyclohexanes (BCH's)

X-ray diffraction measurements have been made on BCH5C1, BCH5Br, BCH5CN, BCH52 and binary mixture of BCH5CN and BCH52, in the nematic phase. BCH5C1 and BCH5Br are thought to have a weak molecular correlation along the texture axis with repeat unit along that axis of ~ 1.1 molecular lengths. Whereas for BCH5CN the repeat unit along the texture axis is about 1.4 molecular lengths implying a stron...

X-ray diffraction studies on merohedrally twinned Δ1–62NtNBCe1-A crystals of the sodium/bicarbonate cotransporter

NBCe1-A membrane-embedded macromolecules that cotransport sodium and bicarbonate ions across the bilayer serve to maintain acid-base homeostasis throughout the body. Defects result in a number of renal and eye disorders, including type-II renal tubular acidosis and cataracts. Here, crystals of a human truncated mutant of the cytoplasmic N-terminal domain of NBCe1 (Δ1-62NtNBCe1-A) are reported t...
