An aldose having n-1 carbon atoms is produced from an aldonic acid having n carbon atoms using hypochlorous acid or a hypochlorite in a high yield at low cost with safety, by treating the reaction mixture with a compound having reactivity with the hypochlorous acid or hypochlorite higher than that with the produced aldose.

Abstract The structure of the K95 antigeniccapsularpolysaccharide (K95 antigen) of Escherichiacoli O75:K95:H5 was elucidated by determination of the composition, 1 H- and 13 C-n.m.r. spectroscopy, periodate oxidation, and methylation analysis. The K95 polysaccharide, which contains furanosidic 3-deoxy- d - manno -2-octulosonic acid (KDO f ) residues, consists of →3)-β- d -Rib-(1→8)-KDO f -(2→ repeating
