text: The lignin in hardwoods is composed of syringyl and guaicyl units in varying ratios; lignin in softwoods is composed of mostly guaiacyl units (more than 95%) and small amounts of p-hydroxyphenyl units, whereas the lignin from agroplants contain all three units (H, G, S) in significant amounts with different ratios, making its structure more complex (del Río et al., 2012).
