Lignin-Derived and Associated Polyphenolic Compounds in Woody Plants: Structural Elucidation, Synthetic Pathways, Characterization Techniques, and Industrial Bioactivities
Lignin is the second most abundant natural biopolymer on Earth, functioning as a primary structural matrix in the secondary cell walls of woody plants. Composed of complex, cross-linked, hydroxylated, and methoxylated phenylpropanoid units, lignin and its associated polyphenols possess unique structural flexibility, UV...
