Lignin and suberin

NettetLignin is a class of complex organic polymers that form key structural materials in the support tissues of most plants. [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 polymers made by cross-linking phenolic precursors. NettetOf the polymers found in plant cell walls, lignin is the only one that is not composed of carbohydrate (sugar) monomers. Suberin is found in the phellem layer of the periderm …
