ALPHA-D-GLUCOSE: PRECISE DETERMINATION OF CRYSTAL AND MOLECULAR STRUCTURE BY NEUTRON-DIFFRACTION ANALYSIS.

This analysis provides the first precise crystal and molecular structural parameters for alpha-D-glucose. The C-C, C-H, and O-H bond lengths deviate only slightly from their means of 1.523 A, 1.098 A, and 0.968 A. The C(1)-O(1) bond length, 1.389 A, is significantly shorter than the mean value, 1.420 A, of the other C-O bonds. The valence angle of the ring oxygen is 113.8 degrees.

SERUM IRON AND IRON-BINDING CAPACITY IN NORMAL SUBJECTS.

Normal values for serum iron and unsaturated iron-binding capacity of serum were established in a carefully selected group of control subjects by a modification of the procedure described by Schade and coworkers. No significant difference was found between mean values in males and females, and there was no correlation between serum iron levels and age in adults. The value of serum iron as a diagnostic aid is limited by the wide range in normal subjects and the large variation that occurs in the same individual from hour to hour and day to day.

SUCROSE: PRECISE DETERMINATION OF CRYSTAL AND MOLECULAR STRUCTURE BY NEUTRON DIFFRACTION.

This analysis provides the first precise molecular parameters for sucrose. All hydrogen atoms are included. Carbon-carbon distances are 1.51 1.53 A; carbon-oxygen 1.40 to 1.44 A; carbon-hydrogen 1.08 to 1.11 A; oxygen-hydrogen 0.94 to 0.99 A. The furanose ring conformation differs from that in sucrose sodium bromide dihydrate. Hydrogen bonds (two of them intramolecular) utilize every hydroxyl group except one.
