Schematic overview of the derivatization of sugar residues by the A alditol acetate, B carbodiimide, and C TMS plant cell wall glycosyl residue composition analysis methods. Schematic depicts analysis of the designated terminal and internal sugars of the indicated plant cell wall polysaccharides: A terminal Rha and internal Man residues, B internal GalA residues of homogalacturonan and Gal residues in β-1,3-linked galactan, C internal GalA and terminal Rha residues. Cyclic and linear sugars are depicted as Haworth and Fischer projections, respectively
