Mead acid is an omega-9 fatty acid, first characterized by James F. Mead.^[1] As with some other omega-9 polyunsaturated fatty acids, animals can make Mead acid de novo. Its elevated presence in the blood is an indication of essential fatty acid deficiency.^[2] Mead acid is found in large quantities in cartilage.
