| Archaeal lipid is composed of sn-glycerol 1-phosphate and isoprenoids. This composition is different from lipid in eubacteria and eukaryotes, which comprises of sn-glycerol 3-phosphate and fatty acids. Responsible enzymes are also non-homologous. Archaea also contains tetraether lipid

| |
| アーキア<cite>古細菌と呼ばれることが多いのですが、真性細菌と明確に区別するためにここではアーキアと記します。</cite>の脂質は、
| |
| sn-グリセロール1リン酸にイソプレン骨格がエーテル結合しています。
| |
| これは、グリセロール3リン酸と脂肪酸を利用する真性細菌や真核生物と全く異なる構造で、生合成をおこなう酵素も相同ではありません。またテトラエーテル型と呼ばれるイソプレン骨格が末端で重合した環状脂質も広く存在し、これが単分子膜を形成すると考えられています。

| |
| アーキアはcrenarchaeotaとeuryarchaetaに分かれますが、
| |
| 特徴からみると三通りになります（表の最左カラム）。
