Lignoceric Ceramide

Lignoceric Ceramide (CAS No.: 34435-05-7) is a long-chain ceramide species and a naturally abundant sphingolipid component of biological membranes, widely studied for its roles in membrane organization and cellular signaling in biomedical research. As a bioactive lipid, it contributes to the structural and functional dynamics of lipid bilayers by inducing lipid phase reorganization, including the formation of ordered gel-like domains, thereby modulating membrane fluidity, permeability, and the spatial distribution of signaling complexes. Functionally, lignoceric ceramide has been implicated in the regulation of diverse cellular processes such as apoptosis, differentiation, and proliferation, and is associated with modulation of mitochondrial activity and membrane-associated signaling pathways. It has also been reported to act as a competitive binding agonist of PIP4K2C, linking it to regulation of the mTOR signaling axis, with downstream effects on cell growth and metabolic control. In experimental systems, this ceramide can influence keratinocyte proliferation and migration, supporting its use in wound healing studies, while altered levels have been associated with cancer cell proliferation and metastasis, highlighting its relevance in oncology research and biomarker discovery. In vitro studies with ceramide analogs generally demonstrate activity in the nanomolar to micromolar range, depending on the cellular context and assay design. Lignoceric ceramide is therefore commonly employed in cell-based assays and membrane biophysics studies to investigate sphingolipid-mediated signaling, lipid raft dynamics, and disease-associated metabolic alterations, with experimental concentrations tailored to specific model systems and research objectives.
