Studies on the structure of soybean glycoprotein

Abstract

Pure fraction PRF3, hydroxyproline-rich glycoprotein, was isolated from soybean cell wall material (dietary fibre) through sodium chlorite-acetic acid (NaClO2-HOAc) extraction and chromatographic column purification. The results of intensive structural characterization showed that PRF3 contained β(1→4) linked galactan backbond which was branched at position 3-C with α(1→3) linked oligoarabinan as side chains, and the polypeptide was glycosidically linked through hydroxyprolinyl arabinosides and serinyl galactosides.

Key words: SODIUM HYPOCHLORITE, GLYCINE MAX, STRUCTURAL ANALYSIS, GLYCOPROTEIN
