Periodate oxidation analysis of carbohydrates. XIII. Simultaneous gas chromatographic determination of the aldehydes in the periodate oxidation products of non-dialyzable urinary carbohydrate materials as diethyl dithioacetals.

The aldehydes in the periodate oxidation products of non-dialyzable urinary carbohydrate materials were determined simultaneously by gas chromatography of their diethyl dithioacetal derivatives. The yields of aldehydes for normal male urine varied considerably among subjects, but their molar ratios were almost constant. The average values for glyceraldehyde/glyoxal and lactaldehyde/glyoxal molar ratios were 0.41 and 0.27, respectively. The average amount of L-fucose at the non-reducing terminals of carbohydrate chains, as estimated from the yield of lactaldehyde, was about 5 mg/day.

Convenient method for the gas chromatographic analysis of hexosamines in the presence of neutral monosaccharides and uronic acids.

A convenient gas chromatographic method has been devised for the analysis of hexosamines in the presence of neutral and acidic sugars, which involves sequential derivatization reactions of nitrous acid deamination, mercaptalation, and trimethylsilylation. This method allows rapid, simultaneous determination of 0.1-1 micromole samples of hexosamines with coefficients of variation of less than 3%.
