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).
Like plant cells, the cells of fungi contain a cell wall, a support  structure which protects the cells in multiple ways including the  prevention of cell lysis or the burstâ¦ing of cells. Unlike plant  cells, however, fungal cells are composed of chitin.
