There is a sample of fish oil that contains 4% of a free fatty acid, 80% of a diglyceride formed by two units of the same fatty acid not yet identified and 16% of unsaponifiable matter. Knowing that the saponification index of the sample is 102.267 mg NaOH / gram oil, deduce and represent the structure of the fatty acid involved Data: Palmitoleic acid (C16: 1), Palmitic acid (C16: 0), Oleic acid (C18: 1), Linoleic acid (C18: 2), Linolenic acid (C18: 3 w3), EPA (C20: 5 w3), DHA (C22: 6 w3).
