I am not sure

Answer 2

Bacterial cell wall is called murein because of the presence of (4) both glucosamine and muramic acid​.

Explanation:

• Peptidoglycan or murein makes up the bacterial cell wall. It is a polymer that is made up of sugars and amino acids.
• N-acetyl glucosamine (NAG) and N-acetyl muramic acid (NAM) alternate as the sugar component . The amino acid chain L-alanine, D-glutamic acid, diaminopimelic acid (DAP) and D-alanine is then connected to NAM.
• It is an extra layer with a semi-rigid structure that often gives some strength that the cell membrane lacks. Peptidoglycan is a component found in both gram positive and gram negative cell walls.
