Six unusual dextrans: methylation structural analysis by combined g.l.c.—m.s. of per-O-acetyl-aldononitriles

Six bacterial dextrans from NRRL strains Leuconostoc mesenteroides B-1299, B-1303. B-1355, and B-1399; Streptobacterium dextranicum B-1254; and A g.l.c. procedure permitted, for the first time. separation of the 2,3,4- from the 2.3.6-tri-O-methyl derivative of d-glucose. Deuteriomethyla
