269. Oxidation of carbohydrates by the periodate ion

Chemical characterization of dissolved organic matter (DOM) in seawater : structure, cycling, and the role of biology

“…The majority of periodate oxidation methods reported in the literature evaluated the extent of reaction based on the measurements of products such as formic acid and formaldehyde via colorimetric analysis (Halsall et al, 1947;Hay et al, 1965;Painter, 1994). Since the periodate oxidation requires the presence of vicinal glycols, for relatively pure monosaccharide and small oligosaccharides, the oxidation products can be traced backwards to give structural information about the original compound and the oxidative yield.…”

A Review of Extraction and Analysis: Methods for Studying Osmoregulants in Plants

“…For colorimetric analysis, mannitol is oxidised with periodic acid in the presence of formic acid [131] and the formaldehyde produced is estimated by colorimetry after coloration with chromotropic acid [132]. As is typical of other colormetric techniques, it is not specific to mannitol and suffers interference from other sugars.…”

Constitution of the Hemicellulose From Mesta Fiber (Hibiscus Cannabinus)

“…The sodium salts of hemicellulose fractions I1 and I11 (0.89 g), in water (60 ml) containing potassiuin chloride (5 g), were oxidized with 0.3 M sodium metaperiodate (30 ml) in the dark a t 10-12" C. The formic acid released was estimated by the procedure of Halsall, Hirst, and Jones (18), which showed that 1 mole of formic acid was produced from 3800 g of the hemicellulose in both the cases.…”
