linoleic acid
Definition
Noun: A polyunsaturated fatty acid that is liquid at room temperature. It is found in high concentrations in many plant-based fats and oils and is classified as an essential fatty acid for human health, meaning the body cannot synthesize it and it must be obtained from the diet. It is also used industrially in the manufacture of soaps.
