| Abstract: | 2-Amino-2-deoxy-D-erythrose was isolated from the cell wall of the fruit body of Agaricus bisporus. The structure of the amino sugar was determined by mass spectrography and 1H-NMR spectrography of its acetylated derivative and by paper chromatographic comparisons with authentic 2-amino-2-deoxy-D-erythrose. This amino sugar is a component of the glycoprotein fraction from the cell wall. Its content in the glycoprotein increased markedly, especially during the ripening stage of the fruit body. |
