Vaccenic acid belongs to the fatty acids and conjugates, a subclass of fatty acyls within the organic compounds. This compound is found in or released from three recorded sources: antennas (electrical & electronic equipment), indoor air (air, dust & atmospheric transport), and the preparation of vinegar (food, food processing & cookware). The recorded route of exposure is inhalation. Regarding its biological activity, vaccenic acid acts as an inhibitor of the protein target peroxisome proliferator-activated receptor delta (PPARD).
