Lignin

Description

Lignin is a complex polymer found in the cell walls of many plant species. Lignin is especially important in the formation of cell ways in rigid and "woody" plant species. Lignin is incredibly rigid, allowing tree species to grow tall, while also allowing for movement of the branches in the presence of stressors such as wind and animal inhabitance.

Structure

Lignin is formed by the crossing of lignols. There are three main types of lignols, conyferal alcohol, sinapyl alcohol, and paracoumaryl alcohol. These lignols are found in all plant species containing lignin, however their abundance will change according to the rigidity and type of the wood they are found in.
