Figure 2. A set of glycan correlation observed in the mass spectrometric analysis of human haptoglobin.

Figure 2

Glycan correlation was displayed on the mass spectrum (A), and illustrated as schematic diagram (B). Symbols in Figure 2(A) were ●, hexose; ◼, N-acetylhexosamine; ▲, fucose; and ◆, N-acetylneuraminic acid. Number in parenthesis on Figure 2(B), are the number of carbohydrate units attached on the molecule X (m/z 35791.10). Number and type of units were calculated from the accurate mass and indicates hexose, N-acetylhexsamine, fucose and N-acetylneuraminic acid from left to right, respectively.
