trans-2-octenoic acid
Notes:
Food flavourant for baked goods and candies
As to unsaturated acids, those with eight carbon atoms, 2-octenoic acid (trans-8: 1[2]) and 2-octynoic acid (8:::1[2]), increase the susceptibility to infection and fluidity while low concentrations of monounsaturated acids with 14 and 18 carbon atoms, myristoleic acid (cis-14:1[9]) and oleic acid (cis-18:1[9]), reduce both the susceptibility to infection and the fluidity of the membrane.
