Lignoceric acid, or tetracosanoic acid, is the saturated fatty acid with formula C₂₃H₄₇COOH. It is found in wood tar, various cerebrosides, and in small amounts in most natural fats. The fatty acids of peanut oil contain small amounts of lignoceric acid (1.1% – 2.2%).^[1] This fatty acid is also a byproduct of lignin production.
