Chem. 169 77 Among the lipide constituents [of nerve tissue] there are at least three, the cerebrosides.., sphingomyelins.., and gangliosides.., which are derivatives of the organic base sphingosine. Sphingosine may also be present in other compounds... As a matter of convenience it is proposed that the term sphingolipide be used to designate these substances. 1978 J. R. Holum Org. & Biol. Chem. xi. 225 The acyl units in the acylamido parts of the sphingolipids are not the usual fatty acids found in neutral fats. sphingolipidosis n.

There are at least three enzyme defects among the sphingolipidoses. 1976 Adv. Exper. Med. & Biol. LXVIII. 9 (caption) Examples of early prenatal diagnoses carried out with the present microtechniques in pregnancies at risk for sphingolipidoses. sphingomyelic adj.

Thudichum in 12th Ann. Rep. Local Govt. Board 1882–3: Rep. Med. Officer 1882 App. b. No. 3. 221 I have for the purposes of the present research isolated and analysed two representatives of this remarkable class of bodies, one amidomyelin..another sphingomyelin, which was found to be..a genuine educt and principle of the brain. 1884 J. L. W. Thudichum Treat. Chem. Constit. 106 Sphingomyelin is the principal..phosphorised ingredient of the so-called cerebrin mixture, which remains when white matter is exhausted by ether. 1884 J. L. W. Thudichum Treat. Chem. Constit. Brain 116 Analysis of Sphingol, a new Alcohol, from Sphingomyelin by Chemolysis with Barita. 1920 J. J. R. Macleod Physiol. & Biochem. (ed. 2) lxxvii. 689 Other phospholipins present in nervous tissue are cephalin, cuorin and sphingo~myelin. 1946 Biol. Rev. XXVI. 285 Sphingomyelins are phosphatides in which the sphingosine or a closely related base is bound by an NHCO linkage to a fatty acid..and by an ester linkage to choline phosphoric acid. 1973 Sci. Amer. Apr. 85/1 The alveolar fluid contains trace amounts of various large molecules; among them are the two principal lipids—lecithin and sphingomyelin—that represent the bulk of the pulmonary surfactant. sphingomyelinic adj.

Brit. /ˈsfɪŋɡə(ʊ)siːn/ , U.S. /ˈsfɪŋɡəˌsin/ (formerly ˈsphingosin) a colourless crystalline base, C18H37NO2, or any of various homologues and derivatives of this, which combined as sphingolipids occur widely in brain and nervous tissue.ΚΠ 1881 J. L. W. Thudichum in Ann. Chem. Med. II. 18 A body remained insoluble which was of an alkaloidal nature, and to which, in commemoration of the many enigmas which it presented to the inquirer, I have given the name of Sphingosin. 1908 W. T. Hall & G. Defren tr. E. Abderhalden Text-bk. Physiol. Chem. ii. 20 On being subjected to hydrolysis this substance took up two molecules of water and formed one molecule of cerebronic acid, one of sphingosine and one of galactose. 1957 Sci. News 45 93 The cerebrosides are found chiefly in the human brain... When hydrolysed they give one molecule each of D-galactose or D-glucose, a fatty acid, and a nitrogenous base, sphingosine. 1968 A. White et al. Princ. Biochem. (ed. 4) iv. 73 Although the above C18 sphingosines are most abundant in sphingolipids, other homologous C16, C17, C19, and C20 sphingosines also are found among the naturally occurring sphingolipids. sphingostearic adj.
