  1. Lipids and Fatty Acids AnusornCherdthong, PhD 137748 Applied Biochemistry in Nutritional Science Email: anusornc@kku.ac.th • E-learning: http://ags.kku.ac.th/eLearning/137748

  2. Lipid nonpolar hydrophobic

  3. Characteristics of Lipids • Nonpolar • Largely hydrophobic. (hydrophobic) insoluble in water but soluble in non-polar organic solvents (such as hexane or ethanol application). • Important component of the cell membrane (cell membrane). • The nutrients. Provide energy source to the body. • The soluble vitamins. Fat soluble such as Vitamin A, D, E and K.

  4. Characteristics of Lipids Lipids (lipid) are organic compound composed of carbon, hydrogen, oxygen, essentially.

  5. Characteristics of Lipids Amphiphile structure OpenStax College (2013)

  6. Characteristics of Lipids Bilayer OpenStax College (2013)

  7. Chemistical process of lipid • Saponification • Halogenation • Hydrogenation • Racidity

  8. Classification of lipid simple compound derivative miscel Fat, oil Phospholipid Fattyacid Sterol Glycolipid Wax Terpene Glycerol Lipoprotein Icosanoid

  9. Characteristics of fatty acid • Consisted of carboxyl and hydrocarbon • Depend on hydrocarbon chain • Cell membrane fond unsaturated FA • Unsaturated FA: • Ciss • Tran • Addition halogen group

  10. Ciss and trans structure OpenStax College (2013)

  11. Classification of fatty acid • Saturated fatty acids • Unsaturated fatty acids • Monounsaturated fatty acids • Polyunsaturated fatty acids) • Eicosanoids • Prostanoids • Leukotrienes

  12. Classification of fatty acid Base on requirement • Non- essential fatty acid • Plamatic, strearic acids • Essential fatty acid • Omega-3 fatty acid • linolenicacid • Eicosapentaenoic acid  • Docosahesaenoic acid  • Omega-6 fatty acid • linoleicacid • arachidonic acid

  13. Relation between FA McDonald et al. (2011)

  14. Micelle Nelson and Cox (2000)

  15. Acylglyceride • Monoacylglyceride • Diacylglyceride • Triacylglyceride

  16. Role of lipid and FA • Energy source • Vitamin soluble • Nutrient storage • Prevent heat • Structure cell membrane • Substance of vitamin and hormone • Blood clotting • Emulsifying agents

  17. 1 2 3 3 Conclusion Characteristics of Lipids Classification of lipid Classification of FA • Role of lipid and FA
