'''Pseudopeptidoglycan''' (also known as '''pseudomurein'''<ref name="White 1995">White, David. (1995) ''The Physiology and Biochemistry of Prokaryotes'', pages 6, 12-21. (Oxford: Oxford University Press). ISBN 0-19-508439-X.</ref>) is a major [[cell wall]] component of some [[archaea]] that differs from [[bacteria]]l [[peptidoglycan]] in chemical structure, but resembles eubacteria peptidoglycan in morphology, function, and structure. The basic components are [[N-acetylglucosamine]] and [[N-acetyltalosaminuronic acid]] (Peptidoglycan has [[N-Acetylmuramic acid|''N''-acetylmuramic acid]] instead), which are linked by a β-1,3-glycosidic bond. Whenever pseudopeptidoglycan is present in an organism, [[lysozyme]] is ineffective. Lysozyme is a host defense mechanism, which can break the B-1,4-glycosidic bonds causing the peptidoglycan to become destroyed. However, pseudopeptidoglycan has the B-1,3-glycosidic bond rendering lysozyme useless.
