=={{Bilingual|スフィンゴ脂質|Sphingolipid}}==
Sphingolipids were first isolated from brain by J.L.W. Thudichum (1829-1901) as lipids of unknown function and structure. The name "sphingo" comes from the Greek word ''sphingein'' for holding tight. (The Sphinx also comes from this word root. <cite>See [http://en.wikipedia.org/wiki/Sphinx the Wikipedia article] in English.</cite>, as well as sphincter muscle.) The basic structure is a long-chain base, usually sphingosine (2-amino-4-octadecene-1,3-diol), whose amino-group is acylated with a long-chain fatty acid. This hydrophobic structure is called ceramides.

スフィンゴ脂質は J.L.W. Thudichum (1829-1901) により機能や構造未知の脂質として脳から見いだされました。スフィンゴという名前はギリシャ語の sphingein に由来しており、「固く縛る」という意味です。(スフィンクスの語源も之に同じで、括約筋のことを英語で sphincter muscle といいます。)基本骨格は長鎖塩基 (長鎖アミノアルコール、通常はスフィンゴシン) のアミノ基が長鎖脂肪酸とアミド結合したもので、セラミドと呼ばれます。

Ceramides with the sphingosine base are prevalent as membrane components of eukaryotic cells. Those with the phytosphingosine base localize in particular organs such as small intestines. Sphingomyelin is a ceramide with phosphocholine.
Major series of phosphosphingolipids are determined by molecules bound to their phosphates, and the series of glycosphingolipids are determined by oligosaccharides bound to their ceramides. The IUPAC series of glycosphingolipids (1977) were based on the order and bonding patterns of four sugars rooting at the long-chain base. Our series, however, are based on three sugars. Two original series, Echino and Schisto, are also added.

|スフィンゴリン脂質はリン酸に結合する分子や糖の種類、スフィンゴ糖脂質はセラミドに結合する糖鎖により系列を作成しています。1977年にIUPACが提唱したスフィンゴ糖脂質の系列は、長鎖塩基に結合する四糖の並びと結合を基準にしています。ここではより広い糖鎖の系列を検索できるよう、三糖を基準に分類しています。また新たにEchinoとSchistoの系列を加えています。
スフィンゴシンをもつセラミドは細胞組織の膜成分として普遍的に存在します。その他にも臓器特異的にフィトスフィンゴシンを含むセラミドが知られています。セラミドにホスフォコリンがついたものが有名なスフィンゴミエリンです。

Sphingolipid

Notation

Page/ID-Code Design

Major series of phosphosphingolipids are determined by molecules bound to their phosphates, and the series of glycosphingolipids are determined by oligosaccharides bound to their ceramides. The IUPAC series of glycosphingolipids (1977) were based on the order and bonding patterns of four sugars rooting at the long-chain base. Our series, however, are based on three sugars. Two original series, Echino and Schisto, are also added.

スフィンゴリン脂質はリン酸に結合する分子や糖の種類、スフィンゴ糖脂質はセラミドに結合する糖鎖により系列を作成しています。1977年にIUPACが提唱したスフィンゴ糖脂質の系列は、長鎖塩基に結合する四糖の並びと結合を基準にしています。ここではより広い糖鎖の系列を検索できるよう、三糖を基準に分類しています。また新たにEchinoとSchistoの系列を加えています。

History of Sphingolipids

Sphingolipids were first isolated from brain by J.L.W. Thudichum (1829-1901) as lipids of unknown function and structure.[1] The basic structure is a long-chain base (long-chain amino-alcohol) whose amino-group is acylated with a long-chain fatty acid. This hydrophobic structure is called ceramides. Sphingolipid consists of phospho-sphingolipid and glyco-sphingolipid, whose ceramide structure is bonded with phosphate and (oligo)saccharides, respectively. Phosphosphingolipid includes sphingomyelin, and glycosphingolipid, cerebrosides and gangliosides. Both are abundant in neural tissues.[2]
