Fig. 5From: Effects of pH on steam explosion extraction of acetylated galactoglucomannan from Norway spruceMALDI-TOF MS spectra of extracted oligosaccharides from the buffer control (black), sodium citrate pH 4.0 (blue), sodium citrate pH 5.0 (red), sodium citrate pH 6.0 (green). Peak labeled 1097.42* is either a double acetylated mannohexose or non-acetylated octapentose. Xyl, xylose; H, hexose; MeGlcUA, methylglucuronic acid; Ac, acetylationBack to article page
