DL-Palmitoylcarnitine (chloride) is a long-chain acylcarnitine with both intracellular and extracellular roles. Within the cell, palmitoylcarnitine is transported into mitochondria to deliver palmitate for fatty acid oxidation and energy production. Exogenously added DL-palmitoylcarnitine alters calcium mobilization in many cell types. It also affects endothelial and epithelial tight junctions, reducing resistance and increasing permeability while decreasing cell viability.
