In General, Lipids in Archaeal Cytoplasmic Membranes Lack True Fatty

Question

In general, lipids in archaeal cytoplasmic membranes lack true fatty acids.

Accepted Answer

Archaeal cytoplasmic membranes are composed of isoprenoid chains instead of fatty acids. These isoprenoid chains are connected to glycerol by ether linkages, whereas in bacteria and eukarya, fatty acids are connected to glycerol by ester linkages.
