Synthesis of Lignin Monomers

Introduction

Lignin is the second most abundant organic polymer. It is found in plants, majorly in trees. Its function is to serve in the assistance of water flow throughout the plant. It forms a barrier for the evaporation, trapping the water inside.

The structure of lignin is composed of the seemingly random combination of three monomers: p-coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol.
