3-Deoxy-d-lyxo-heptulosaric acid (DHA) has been identified as a component of plant cell walls. This sugar was found in the pectic polysaccharide rhmanogalacturonan-II as a component of the disaccharide β-l-Araf-(1→5)-d-DHAp. The structural formula and linkage position of DHA were determined by mass spectrometry of several derivatives. The lyxo configuration was determined by 1H-n.m.r. spectroscopy of a derivative of the isolated disaccharide. The d configuration was determined by partial degradation of DHA to l-glyceric acid. DHA was found to be present in the primary cell walls of many higher plants, including several dicots, two monocots, and a gymnosperm, but was not detected in two bacterial lipopolysaccharides.
