Bushings are one of those things that most people don't really think about until they find out they have a $600 mechanic's repair bill on their hands. Some even think the mechanic is trying to rip them off when they mention bushings needing replaced.
Lignin is a phenolic compound, chemically related to benzene. The cell walls of fungi are diverse among the taxonomic groups, but most contain chitin microfibrils embedded in a polysaccharide matrix and covered with a loose coating of additional molecules combining sugars and peptides (amino acid chains).
The cell walls of fungi are made of chitin and other polymers, especially glucans, which are long chains of glucose. Chitin plays the same role in fungal cell walls as cellulose does in plant cell...
