Final answer:
The two sugars found in pseudo*eptidoglycan of archaea are N-acetylglucosamine (NAG) and N-acetyltalosaminuronic acid (NATA).
Step-by-step explanation:
Two sugars are identified in the pseudo-peptidoglycan of archaea: N-acetylglucosamine (NAG) and N-acetyltalosaminuronic acid (NAT). The peptidoglycan found in bacteria is composed of N-acetylmuramic acid (NAM), but the peptidoglycan found in archaea contains NAT instead of NAM.
The common component of the cell walls of both bacteria and archaea is N-acetylglucosamine, but the archaeal pseudo-peptidoglycan is the only one that contains N-acetyltalosaminuronic acid. Pseudo-peptidoglycan's composition contributes to these activities differently from that of bacterial peptidoglycan, and it is essential for archaea to maintain cell structure, resist environmental stresses, and protect the organism.
