Both occur in lignin, and are then undoubtedly indigestible.
A powder of similar composition is produced by the action of powerful chemical reagents on sugar, lignin, &c.
Any number of things: Perhaps the lignin in the nerve paths was poisonous.
Ligneous, or woody tissue (lignin) is indurated cellulose, hardened by age.
Like tropical rains from a jungle roof, lignin dripped from the vaults, and in falling, burst into flames.
With the third blow the plastics cell cracked and the lignin poured out, a syrupy curtain sliding down.
In the second year the lignin alone increased to the end; the cellulose decreased at the end of June.
But in wood fiber the cellulose is in part combined with lignin, which is worse than useless.
