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

3 Γλυκερίδια Λίπη-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

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

15 Conjugated Linoleic Acid

16 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.”
