Sphingolipid

Class Overview

Sphingosine & Ceramide

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.
The Sphingolipid category (LBS) in this database includes glycosphingolipid, phosphosphingolipid, and ceramide.

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。
このデータベースにおけるスフィンゴ脂質カテゴリー (LBS) には、スフィンゴ糖脂質 (glycosphingolipid)、スフィンゴリン脂質 (phosphosphingolipid) 、セラミド (ceramide) が含まれています。
