Ceramide - Wikipedia
Ceramides are a family of waxy lipid molecules. A ceramide is composed of sphingosine and a fatty acid joined by an amide bond. Ceramides are found in high concentrations within the cell membrane of eukaryotic cells, since they are component lipids that make up sphingomyelin, one of the major lipids in the lipid bilayer. [1]
Ceramide - an overview | ScienceDirect Topics
Structure of a ceramide molecule. Ceramide contains an N -acylated (14–26 carbons) sphingosine (18 carbons). Carbons 1–5 of the sphingosine backbone consist of hydroxyl groups at C1 and C3, a trans double bond across C4 and C5, and an amide group that serves as the fatty acyl linkage at C2.
