Erucic acid is a monounsaturated omega-9 fatty acid, denoted 22:1ω9. It has the chemical formula: CH_₃(CH₂)₇CH=CH(CH₂)₁₁CO₂H. It is prevalent in wallflower seed and other plants in the family Brassicaceae, with a reported content of 20 to 54% in high erucic acid rapeseed oil^[2] and 42% in mustard oil. Erucic acid is also known as cis-13-docosenoic acid and the trans isomer is known as brassidic acid. Cetoleic acid is a positional isomer of erucic acid.
