Lignoceric acid, also known as tetracosanoic acid, is a straight-chain saturated fatty acid containing 24 carbon atoms. It occurs naturally in small amounts in various plant oils such as peanut oil and in animal tissues, particularly as a component of sphingolipids and cerebrosides in the myelin sheath of nerve fibers. Due to its long hydrocarbon chain, it exhibits a high melting point and low volatility. It plays roles in lipid metabolism and is studied in contexts of peroxisomal disorders where its accumulation can occur. As a food-derived compound, it contributes to the fatty acid profile of certain edible oils and fats.
