  12. Fatty Acid Composition of Different Oils

  13. Constitution of olive oilFatty acids 1. Oleic (C18:1) 2. Linoleic (C18:2) 3. Linolenic (C18:3) 4. Arachidonic (C20:4) 5. Palmitoleic (C16:1) 6. Palmitic (C16:0) 7. Stearic (C18:0)

  14. Vitamin Α Vitamin Ε Provitamin Α α-caroten β-caroten Phytosterols Saponins Coumarins Dithiones Indols Terpens Isoflavones Polyphenols Phylic acin Proteases inhibitors Olive oil constitutionOther ingredients

  15. Effect of Olive oil on cell function • Replacement of saturated fatty acids from cell walls (better cell plasticity) • Import of antioxidant microconstituents (ex. Vitamin A, Vitamin E) and decrease of oxidized lipids. • Replacement of oxidized lipids from vessel walls.
