What is lignin? Lignin is a complex polymer composed primarily of carbon, hydrogen and oxygen. It is in the plant cell wall and is responsible for giving them rigidity and resistance. Unlike cellulose, which is …

Lignin is an incredibly important yet often underappreciated organic material, found in copious amounts throughout the world. This complex compound is mainly sourced from the cell walls of vascular …

Lignin is a natural biopolymer. In nature, it only exists as part of lignocellulose - alongside cellulose and hemicelluloses. Let’s first have a look at what lignin is chemically and how it is formed in nature.

What is lignin? Lignin from the Latin word lignum, which means “wood,” refers to the importance of the molecule in the structure of wood and plants. Lignin, the second most abundant polymer in the world, …
