From: Mannanase hydrolysis of spruce galactoglucomannan focusing on the influence of acetylation on enzymatic mannan degradation

Fig. 1

Chemical structures: a spruce O-acetyl-galactoglucomannan (SpGGM), b konjac glucomannan (KGM), and c locust bean gum galactomannan (LBG). C2 and C3 are potential acetylation sites (marked in red) on the SpGGM and KGM mannose units. Average monosaccharide ratios of mannose (green), glucose (blue), and galactose (yellow), and degree of substitution by acetylation (DSac) are shown for each mannan. The degree of substitution on glucose or mannose units in KGM is low (8%). KGM is therefore referred to as a linear polysaccharide, compared with the highly substituted LBG and SpGGM
