Neuraminic acid. IV. Gas-Liquid Chromatography of N-Acetyl- and N-Glycolylneuraminic Acids

Abstract

The behaviour of N-Glycolylneuraminic acid in comparison with N-Acetylneuraminic and glucose and N-acetylglucosamine has been studied by gas-liquid chromatography. With methanol-HCl treatment, previous to sylanization, both acylneuraminic acids derivatives give the same peak. With sylanization only, N-Glycolylneuraminic acid does not give any characteristical peak.

A brief discussion is made on these facts.
