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).
Cell walls are composed of cellulose, what is colloquially called fiber. It is a polysaccharide made of glucose monomers. It has beta glucose chains contrasting with the alp â¦ ha glucose of starch. Because of its bond structure, the chain is indigestible for most organisms and provides rigid support.
