Archaeal membranes and cell wall Archaea lack fatty acids, instead have hydrocarbon moieties bonded to glycerol by ether (instead of ester) linkages Glycerol diethers and diglycerol tetraethers are the major classes of lipids present in Archaea Archaea do not contain muramic acid and D-amino acids. as in Bacteria A pseudopeptidoglycan is found in some archaea, it consists of two amino sugars: N-acetylglucosamine and N acetyltalosaminuronic acid, with only L-amino acids lin kages Some contain a thick wall consists only polysaccharide Some contain cell walls made of glycoprotein Some lack carbohydrate in their cell walls and have walls consisting of only protein.Archaeal Membranes and Cell Wall Archaea lack fatty acids, instead have hydrocarbon moieties bonded to glycerol by ether (instead of ester) linkages Glycerol diethers and diglycerol tetraethers are the major classes of lipids present in Archaea Archaea do not contain muramic acid and D-amino acids, as in Bacteria A pseudopeptidoglycan is found in some archaea, it consists of two amino sugars: N-acetylglucosamine and N￾acetyltalosaminuronic acid, with only L-amino acids linkages Some contain a thick wall consists only polysaccharide Some contain cell walls made of glycoprotein Some lack carbohydrate in their cell walls and have walls consisting of only protein
