Relative monosaccharide and lignin composition of untreated wood (Eucalyptus and Spruce) and holocellulose samples. Values represent the relative weight of the corresponding monosaccharide from acid hydrolysis and the measured lignin after the acetyl bromide dissolution in the total weight of the biomass sample. 4O-MeGlcA (4-O-methyl-D-glucuronic acid); GalA (galacturonic acid); GlcA (glucuronic acid)
