Sphingolipid (スフィンゴ脂質)
Class Overview
Sphingosine is synthesized from decarboxylating condensation of palmitoyl CoA with serine. It is a 18-carbon amino alcohol (16 carbons from palmitic acid and 2 from serine) with one unsaturated bond (2-amino-4-octadecene-1,3-diol). Sphingosine is further acylated to form ceramide, an important component of cell membranes.

スフィンゴシンはパルミトイルCoAがアミノ酸セリンと脱炭酸縮合して生成します。炭素を18個含むアミノアルコール(16個がパルミチン酸、2個がセリン由来)で不飽和結合を1つ含んでいます (2-amino-4-octadecene-1,3-diol)。
スフィンゴシンがアシル化したものが、細胞膜の重要な成分であるセラミドです。

Classification
By the Number of Sugars 糖の個数
For glycosphingolipid, 2 digits following LBS stand for the number of attached sugars. For phosphosphingolipid, the code of phosphorylation, PP. |
スフィンゴ糖脂質は結合している糖の総数をLBSに続く2桁の数字で、スフィンゴリン脂質は数字の代わりにリン酸化修飾を示す記号PPで分類しています。 |
