Bacteria and yeast differ from each due to the different chemical composition of their cell wall.
Chitin: chitin is a large structural polysaccharide that is derived from chains of modified glucose. It is the primary components of cell wall in fungi such as yeast. Chitin is a minor component in the yeast cell wall, it accounts for only 1-2% of the cell wall dry mass. Chitin contributes to the mechanical strength of the cell wall.
Peptidoglycan: Peptidoglycan also known as murein is a polymer that makes up a the cell wall of a bacterium. It is composed of sugars and amino acids. A bacteria is a unicellular organism, therefore Peptidoglycan gives strength to the outer structure of the organism.
The chemical compounds that distinguish bacteria cell from yeast cell are
chitin and murein
Chitin is a polysaccharide present in the exoskeleton of fungi made up of chains of modified glucose known as N-acetylglucosamine. N-acetylglucosamine is derived from glucose
While murein is a mesh like structure made up of sugar and amino acids. Murein forms a layer outside the plasma membrane of bacterial cell.
