    Product Description

    9(Z),12(Z),15(Z),18(Z),21(Z)-Tetracosapentaenoic acid is an ω-3 very long-chain polyunsaturated fatty acid. It has been used to study the desaturation and elongation of ω-3 polyunsaturated fatty acids.1 It is elongated to form C26:5 or acted on by Δ6 desaturase to form C24:6. 9(Z),12(Z),15(Z),18(Z),21(Z)-Tetracosapentaenoic acid is found at low levels in mouse brain and spleen and levels decrease in the brain and spleen of old and exceptionally old mice.2
