Wood Science 101(3) - Lignin

Description:
You'd be hard pressed to find a material more universally researched right now than lignin. It's the second most abundant organic polymer on earth, behind cellulose. It's what makes trees stand upright, what makes wood hold its shape, and what makes furniture support your weight when you sit on it. Lignin is everywhere in the biological realm, plays a huge part in maintaining the earth's carbon cycle, and therefore, the environmental stability of the world, and is still one of the primary foci of the world's scientific community.
