单词	sphingosine
释义	sphingosine sphin·go·sine S0634175 (sfĭng′gə-sēn′)n. A basic, long-chain, unsaturated amino alcohol, C₁₈H₃₇NO₂, that combines with lipids to form sphingolipids. [German Sphingosin : Greek sphingos, genitive of sphinx, sphinx (from the mysteries it presented to early observers) + -ine.] sphingosine (ˈsfɪŋɡəsɪn; -ˌsiːn) n (Biochemistry) biochem a long-chain compound occurring in sphingomyelins and cerebrosides, and from which it can be released by hydrolysis. Formula: CH3(CH2)12CH:CHCH(OH)CH(NH2)CH2OH[from sphingos-, from Greek sphingein to hold fast + -ine²] Sphingosine sphingosine [′sfiŋ·gə‚sēn] (biochemistry) C₁₈H₃₇O₂N A moiety of sphingomyelin, cerebrosides, and certain other phosphatides. Sphingosine an unsaturated higher aliphatic amino alcohol, C₁₃H₂₇CH=CHCH(OH)CH(NH₂)CH₂OH. Sphingosine is soluble in organic solvents and insoluble in water; its melting point is 81.5°–83°C, and its properties are those of a base. Sphingosine occurs in nature as a constituent of sphingolipids. Its biosynthesis in cells is effected from the amino acid serine and palmitic acid with the participation of coenzyme A. Sphingosine exhibits an anticoagulant effect since it inhibits the conversion of prothrom-bin to thrombin. The more than 60 analogues of sphingosine— sphingosine bases—are distinguished by the length of the aliphatic chain, the degree of nonsaturation, the type of branching, and the location of the double bond. sphingosine sphingosine [sfing´go-sēn] a basic amino alcohol present in sphingomyelin. sphin·go·sine (sfing'gō-sēn), The principal long-chain base found in sphingolipids. Synonym(s): , sphingol sphingosine (sfĭng′gə-sēn′)n. A basic, long-chain, unsaturated amino alcohol, C₁₈H₃₇NO₂, that combines with lipids to form sphingolipids. sphin·go·sine (sfing'gō-sēn) The principal long-chain base found in sphingolipids.
