Polysaccharides make up about 90% of the cell wall composition, with proteins, enzymes, and fatty acids making up the remaining components of about 10%.
Generally speaking, the main component of the cell wall of bacteria is peptidoglycan, or mucopolysaccharide; the main component of the cell wall of plant cells is pectin and cellulose; the main component of the cell wall of fungi is beta-1,3-glucan and chitin.
1. The cell wall is located outside the cell membrane with elasticity of a layer of structure, mainly mucus complex. Polysaccharides such as cellulose, hemicellulose and pectin accounted for about 90%, proteins, enzymes and fatty acids and other components accounted for about 10%.
2. The main component of the bacterial cell wall is peptidoglycan, which has the function of protecting the bacteria against the hypotonic environment and maintaining the intrinsic form of the bacteria, and also participates in the exchange of substances and determines the antigenicity of the bacterial organism.
3. The main components of the cell wall of plant cells are cellulose and pectin; the main components of the cell wall of fungi are chitin and beta-1,3-glucan, so most fungi can be killed by chitinase or glucanolytic enzymes.
The composition of the cell wall is complex, please refer to authoritative books and ask the relevant personnel for specific knowledge.
