several scientists have determined the composition of plant root mucilage using monosaccharide analysis and linkage analysis, showing that maize (zea mays) root mucilage contains high levels of galactose, xylose, arabinose, rhamnose, and glucose, and lower levels of uronic acid, mannose, fucose, and glucuronic acid. wheat (triticum aestivum) root mucilage also contains high levels of xylose, arabinose, galactose, glucose, and lower levels of rhamnose, glucuronic acid and mannose. cowpea (vigna unguiculata) also contains high levels of arabinose, galactose, glucose, fucose, and xylose, and lower levels of rhamnose, mannose, and glucuronic acid. many other plants have had their root mucilage composition determined using monosaccharide analysis and monosaccharide linkage analysis. with the following monosaccharides determined as well as their linkages, scientists have determined the presence of pectin, arabinogalactan proteins, xyloglucan, arabinan, and xylan, which are plant-specific polysaccharides within the root mucilage of plants.
