Presentation Transcript

  1. ΛΙΠΙΔΙΑ • Ορισμός • A group of compounds that are soluble in certain organic solvents such as Ether, Benzene, and Chloroform, and are insoluble in water

  2. ΛΙΠΙΔΙΑ ΥΔΡΟΛΥΌΜΕΝΑ (Παρουσία εστερικού δεσμού) ΜΗ ΥΔΡΟΛΥΟΜΕΝΑ (Απουσία εστερικού δεσμού) Κηροί Γλυκερίδια Στεροειδή Προσταγλανδίνες Λίπη-Έλαια Φωσφολιπίδια

  3. ΓλυκερίδιαΛίπη-Έλαια • Fat: solid at room temperature • Oil: liquid at room temperature Glycerol + 3 Fatty Acids Triglyceride

  4. ΛΙΠΑΡΑ ΟΞΕΑ • With a few exceptions, natural fatty acids: • Contain an even number of carbon atoms • Arranged in an un-branched line • Have a carboxyl group (-COOH) at the end

  5. ΚΟΡΕΣΜΕΝΑ ΑΚΟΡΕΣΤΑ

  6. Omega System • Delta system: carbon atom in a fatty acid is numbered from the carboxyl end • Omega system: carbon atom is numbered from the methyl end

  7. Omega System C-C-C=C-C-C=C-C-C=C-C-C-C-C-C-C-C-COOH Animal can put in a double bond in the omega 9 position but not at either 3 or 6 Cold water fish accumulate a lot of omega 3 fatty acids from their diet Ω-3 Ω-6 Ω-9

  8. ΡΟΛΟΣ ΤΩΝ ω-3 ΛΙΠΑΡΩΝ ΟΞΕΩΝ • ΣΤΗΝ ΥΓΕΙΑ ΚΑΙ ΤΙΣ ΧΡΟΝΙΕΣ ΠΑΘΗΣΕΙΣ • Στην φυσιολογική ανάπτυξη • Στην πρόληψη και την θεραπεία της στεφανιαίας νόσου • Στην υπέρταση • Στον διαβήτη • Στην αρθρίτιδα • Στις φλεγμονώδεις ασθένειες και • Στον καρκίνο

  9. ΑΠΑΡΑΙΤΗΤΑ ΛΙΠΑΡΑ ΟΞΕΑ • Added fat to the diet • Butter and coconut oil---no effect • Olive oil---no effect • Corn and linseed oil---very effective

  10. ΣΥΣΧΕΤΙΣΗ ΒΑΘΜΟΥ ΑΚΟΡΕΣΤΟΤΗΤΑΣ ΚΑΙ ΣΗΜΕΙΟΥ ΤΗΞΕΟΣ

  11. Conjugated Linoleic Acid trans 10, cis 12 CLA cis 9, trans 11 CLA linoleic acid

  12. Conjugated Linoleic Acid • Product of normal fermentation in the rumen • Found in the muscle and milk of ruminant species • Has human health benefits

  13. Conjugated Linoleic Acid

  14. CLA May Prevent Breast Cancer • The addition of two glasses of milk per day in a Finnish study significantly reduced the risk of breast cancer. • This was an increase of 55mg/d of CLA. • “If margarine was replaced by butter in the American diet it would increase CLA intake by approximately 54mg/day.”

  15. Digestion

  16. ΣΑΠΩΝΕΣ

  17. ΑΠΟΡΥΠΑΝΤΙΚΗ ΔΡΑΣΗ ΣΥΝΘΕΤΙΚΑ ΑΠΟΡΥΠΑΝΤΙΚΑ

  18. ΦΩΣΦΟΛΙΠΙΔΙΑ

  19. ΝΟΥΚΛΕΪΝΙΚΑ ΟΞΕΑ
