L-Idose is a 6 carbon monosaccharide(a hexose) It has an aldehyde group and is an aldose. It is not found in nature, but its uronic acid, iduronic acid is important. It is a component of dermatan sulfate and heparan sulfate, which are glycosaminoglycans. The first and third hydroxyls point the opposite way fron the second and fourth. It is made by aldol condensation of D- and -L glyceraldehyde. Idose is a C-5 epimer of D-glucose./ Jump to: navigation, search This article needs to be cleaned up to conform to a higher standard of quality. ...

The linkage to ceramide is a direct or covalent linkage between the sugar and ceramide, preferably a beta-1 linkage of the sugar moiety to ceramide.
The saccharide units for position R include but are not limited to galactose, allose, altrose, mannose, gulose, idose, talose and the like, provided the net charge of the glycolipid remains neutral and the neutral glycolipid maintains antithrombotic activity.
The number of carbon atoms in the fatty acid chain may vary and may include, for example 16, 18, 22 or 24 carbon atoms, provided the polar head groups of OH at C-3 and amide group at C-2 of ceramide is maintained.
