In which of the following structures are composed of N-acetylmuramic acid and N- acetylglucosamine?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) - Bacterial cell wall
The cell wall of gram-negative bacteria is made up of a thin layer of peptidoglycan which is also known as murein.
N-Acetylmuramic acid is the ether of lactic acid and N-acetylglucosamine.
It is present in the bacterial cell wall which is formed by the cross-linking of alternating units of N-acetylglucosamine and N-acetylmuramic acid.
