B) Starch
C) Lignin
D) None of these choices

Respuesta :

Lignin is a relatively indigestible strengthening polymer that makes up more than a quarter of wood's dry mass.

What is Lignin?

Lignin is a complex organic polymer that forms key structural materials in most plant support tissues. Lignins play an important role in the formation of cell walls, particularly in wood and bark, because they provide rigidity and do not rot easily.

Types of Lignin :

Soda lignin, Kraft lignin, hydrolyzed lignin, organosolv lignin, and lignosulfonates are the most common types of lignin. Alberta Pacific, Borregaard LignoTech, CIMV, Domtar, Domsjö, Tembec, UPM, and Weyerhaeuser are among the major manufacturers of these products.
