Lignoceric ceramide (CAS 34435-05-7)

Lignoceric ceramide, characterized by its long-chain lignoceric acid (a saturated fatty acid with 24 carbon atoms) amide-linked to a sphingosine base, is a critical component of the lipid matrix in the stratum corneum of the skin, as well as part of the complex lipid composition in the nervous system. This ceramide plays a significant role in maintaining the barrier function and structural integrity of cell membranes, particularly in the epidermis, where it contributes to moisture retention and protection against environmental factors. In research, lignoceric ceramide has been used to study the biomechanical properties of cell membranes and lipid layers, offering insights into the role of specific ceramides in cell signaling and membrane stability. Its presence affects the viscosity and phase behavior of lipid bilayers, which are crucial for cellular processes like vesicle formation, fusion, and the proper functioning of membrane-bound enzymes and receptors. Additionally, investigations into lignoceric ceramide′s interactions with other lipid species help explain the mechanisms by which lipid composition can influence cellular communication and metabolic regulation. Such studies are vital for understanding the biochemical pathways that govern cell physiology and the maintenance of cellular homeostasis under various physiological conditions.
