Further examples of applications could be given for the optimal S/G ratio and amounts of carbohydrates in lignin (present as LCC). For instance, a higher proportions of S-units should be beneficial for lignin depolymerization due to the higher reactivity of S-units compared to that of G-units . In contrast, S-units are not suitable for various crosslinking reactions as both orthopositions to the phenolic OH (typical reaction centers in crosslinking) in the aromatic ring of S-units are occupied by OMe-groups . In surfactant applications, the pres-ence of hydrophilic carbohydrates moieties (as LCC) can be advantageous, while, e.g., the production of aromatic monomers requires high purity lignin .
