Sphingolipids were first isolated from brain by J.L.W. Thudichum (1829-1901) as lipids of unknown function and structure.<ref>Thudichum J.L.W. "A Treatise on the Chemical Constitution of the Balliere" Tindall and Cox, London, 1884</ref> 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 (poly)saccharides, respectively. Phosphosphingolipid includes sphingomyelin, and glycosphingolipid, cerebrosides and gangliosides. Both are abundant in neural tissues.<ref>Gault CR, Obeid LM, Hannun YA "An overview of sphingolipid synthesis to breakdown" Adv Exp Med Biol. 2010;688:1-23. PMID 20919643</ref> | |||

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。基本骨格は長鎖塩基 (長鎖アミノアルコール) 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。 | |||
スフィンゴ脂質はセラミドにリン酸が結合したスフィンゴリン脂質と糖が結合したスフィンゴ糖脂質に分けられます。スフィンゴリン脂質にはスフィンゴミエリンが、スフィンゴ糖脂質にはセレブロシドやガングリオシドなどが含まれ、いずれも神経系に多く存在します。 | |||

Major series of phosphosphingolipids are determined by molecules bound to their phosphates, and the series of glycosphingolipids are determined by polysaccharides 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. | |||

Sphingosine is synthesized from decarboxylating condensation of palmitoyl CoA with serine on the ER membrane. It is a 18-carbon amino alcohol (16 carbons from palmitic acid and 2 from serine) with one unsaturated bond (trans-form) at the C-4 position (2-amino-4-octadecene-1,3-diol).

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 (poly)saccharides, respectively. Phosphosphingolipid includes sphingomyelin, and glycosphingolipid, cerebrosides and gangliosides. Both are abundant in neural tissues.[2] |

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 polysaccharides 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。 |
