A class of glycosphingolipid; specifically, a monoglycosylceramide (ceramide monosaccharide), the sugar being attached to the &cbond;CHOH&cbond; moiety of the sphingoid. Cerebrosides are found in the myelin sheath of nerve tissue; e.g., kerasin, nervon, oxynervon, phrenosin, these names also being used for the fatty acid involved. C. is sometimes prefixed by gluco-, galacto-, etc., in place of the correct glucosylceramide, etc. The sulfate esters of cerebrosides are among the sulfatidates. c.-sulfatase, c. sulfatidase an enzyme that cleaves sulfate from a sulfated glycosphingolipid (such as a c. 3-sulfate).

A genus of marine and brackish water operculate (prosobranch) snails that serve as first intermediate hosts of a number of trematodes. C. cingulata serves as host for Heterophyes heterophyes in Japan and Southeast Asia; C. scalariformis for cercariae that induce swimmer's itch in the southeastern U.S. from Florida to Texas.

Wax. [L. cera, wax]
A waxlike, golden or yellow-brown pigment first found in fibrotic livers of choline-deficient rats, and also known to be present in some of the cirrhotic livers (and certain other tissues) of human beings. C. is acid fast, insoluble in fat solvents, and probably a type of lipofuscin, although differing from true lipofuscins by failing to stain with Schmorl ferric-ferricyanide reduction stain; it also exhibits autofluorescence. Accumulates in Hermansky-Pudlak syndrome. [L. cera, wax, + G. eidos, appearance]
The manufacture of wax models of anatomic and pathologic specimens or of skin lesions. [G. keros, wax, + plasso, to mold]
