Lignin is the most abundant natural aromatic polymer. It is one of the major cell-wall components of wood and grass species, along with cellulose and hemicellulose. It is a polyether derived from coniferyl, p-coumaryl, and sinapyl alcohols, among others. Lignin has several industrial uses, including fuel, pulp for newsprint, and multi-use lignosulfonates, a pulp byproduct. Lignin decomposition products in the paper of old books give secondhand bookstores their appealing odor.
