Is it true that archaeal cell membranes contain isoprene chains linked to glycerol instead of the fatty acids linked to glycerol found in bacterial membranes?

Yes. Archaeal cell membranes are characterized by isoprenoid chains linked to glycerol, contrasting with the fatty acid chains found in bacterial membranes.
