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).
Simply Cell wall of plant is composed of cellulose whlie that of Fungi is composed of Chitin The main carbohydrate that composes plant cell wall is glucose (linked in Î² 1-4 linkages forming cellulose). In Fungi, the main carbohydrate that composes the cell wall is N-acetylglucosamine (linked in Î² 1-4 linkages forming chitin). There are also other differences. Plant cell wall is also composed of Pectins, Hemicellulose, and Lignin (mainly in plants that have trunks). None of these molecules appear in fungi walls.
