Lignin - Wikipedia

Lignin is a class of complex organic polymers that form key structural materials in the support tissues of vascular plants and some algae. 1 Lignins are particularly important in the formation of cell walls especially in wood and bark because they lend rigidity and do not rot easily. Chemically lignins are cross-linked phenolic polymers. 2 History& 0183;& 32;
