Source sentences:
text: However, using kraft lignin to produce high value-added products is a great challenge, due to its complex structure, low reactivity, and low solubility, which are factors that limit the lignin’s large-scale use in biorefineries.
text: As a result of the random polymerization of phenylpropane monomers, lignin adopts complex three-dimensional structures with various types of functionality.

text: The thermal degradation of lignin occurred over a wide temperature range (200 to 400 °C) and can be explained by the fact that lignin presented a complex structure made up of phenolic hydroxyl, carbonyl groups, and benzylic hydroxyl, interlinked by various types of chemical linkages, which are connected by straight carbon-to-carbon links (Sjöström 1993; Domínguez et al. 2008).
text: The structure of lignin is complex and its characterization difficult.
text: (1) Lignin has a complex structure originating from hydrogenative polymerization of three basic precursors, namely,-hydroxyphenyl (H), coniferyl (G), and sinapyl (S) alcohols.
text: We don’t get to see its complex structures because they are broken into pieces when it is extracted from a plant –
text: It is composed of guaiacyl, syringyl, and-hydroxyphenyl monomers linked by C–O and C–C bonds and has a complex three-dimensional structure.
