Common Name(10E,12Z)-(9S)-9-Hydroperoxyoctadeca-10,12-dienoic acid
Description(10E,12Z)-(9S)-9-Hydroperoxyoctadeca-10,12-dienoic acid, also known as 9(S)-HPOD or (9S,10E,12Z)-9-Hydroperoxy-10,12-octadecadienoate, is classified as a lineolic acid or a Lineolic acid derivative. Lineolic acids are derivatives of lineolic acid. Lineolic acid is a polyunsaturated omega-6 18 carbon long fatty acid, with two CC double bonds at the 9- and 12-positions. (10E,12Z)-(9S)-9-Hydroperoxyoctadeca-10,12-dienoic acid is considered to be practically insoluble (in water) and acidic. (10E,12Z)-(9S)-9-Hydroperoxyoctadeca-10,12-dienoic acid is an octadecanoid lipid molecule. (10E,12Z)-(9S)-9-Hydroperoxyoctadeca-10,12-dienoic acid can be found throughout numerous foods such as Barley, Prunus (Cherry, Plum), Cherimoya, and Prairie turnips
