Several metal-sugar conjugates have been prepared. Chelate coordination complexes of copper(I1) and zinc(H) were prepared from salicylaldimine ligands derived from combinations of methyl 3,4,6-tri-0-acetyl-2-amino-2-deoxy-@glucopyranoside or 1,3,4,~tetra-O-acetyl-2-amino-2-deoxy-&D-gluoopyranose and

✦ Synopsis
Although the crystalline X-ray patterns of starch have been known for many years from the pioneering work of Katz and Van Italie', their interpretation has lagged behind that of cellulose because of hydration phenomena. Cereal starches give a pattern classed as 'A" and the starches of tubers yield a "B" pattern. The presence of water favors starch
