Metabolite Identification
Common NameCalendic acid
DescriptionCalendic acid, also known as a-calendate or C18:3N-6,8,10, belongs to the class of organic compounds known as lineolic acids and derivatives. These 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. Calendic acid exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule.
