Archaeal Lipid
Upper classes:
LB
Class Overview
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。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。
|
Archaea are separated into two phyla which show three different characters (Table 1: leftmost column).
|
アーキアの系統は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）。

Design of Fat acyl Page Titles
Each page title contains chain-length, degree of unsaturation, position of double bonds, and backbone structure (branches, peroxidation, or prostanoids etc.).
|
各分子のページタイトルに鎖長、不飽和度、二重結合の位置、骨格タイプ（分岐や過酸化、プロスタノイドなど）がコード化されています。
