Ceramides (pronounced ser-A-mid OR seramide) are a family of waxy lipid molecules. A ceramide is composed of sphingosine and a fatty acid . Ceramides are found in high concentrations within the cell membrane of cells. They are one of the component lipids that make up sphingomyelin , one of the major lipids in the lipid bilayer . Contrary to previous assumptions that ceramides and other sphingolipids found in cell membrane were purely structural elements, ceramide can participate in a variety of cellular signaling : examples include regulating differentiation , proliferation , and programmed cell death (PCD) of cells .The word ceramide comes from the Latin cera ( wax ) and amide . Ceramide is a component of vernix caseosa , the waxy or cheese-like white substance found coating the skin of newborn human infants
use
Ceramide is one of the main components of the epidermis layer of human skin. Together with cholesterol and saturated fatty acids, ceramide creates a water-impermeable, protective organ to prevent excessive water loss due to evaporation
As a bioactive lipid, ceramide has been implicated in a variety of physiological functions including apoptosis , cell growth arrest, differentiation, cell senescence , cell migration and adhesion. Roles for ceramide and its downstream metabolites have also been suggested in a number of pathological states including cancer , neurodegeneration , diabetes , microbial pathogenesis, obesity , and inflammation
