Glucopyranose monohydrate, crystal structure

The hydrogen bonding in melibiose monohydrate includes a homodromic cycle. Cyclic hydrogen-bonding schemes are not common in mono- and disaccharides, but in the crystal structure of the epimeric a,yS-melibiose monohydrate, 6-0-a-D-galactopyranosyl-cr,/ -D-glucopyranose-H20 [MELIBM01] (Fig. 13.49),... 

These crystal-structure analyses are concerned with the following molecules o-D-glucopyranose monohydrate/ D-xylopyranose/ methyl yS-D-xylopyranoside, di-jS-n-fructopyranose-strontium chloride trihydrate, cellobiose (independent determination), D-glucaric acid, D-galactonic acid, methyl a-D-lyxofuranoside, /3-D-lyxopyranose, methyl 3,4,6-tri-0 - acetyl - 2 - (chloromercuri) - 2 - deoxy - j3 - d - glucopyranoside, D-glu-copyranosyl (potassium sodium phosphate) tetrahydrate," and methyl 6-bromo-6-deoxy-a-D-galactopyranoside. ...
