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 OpenStax College (2013) Amphiphile structure

6. Characteristics of Lipids OpenStax College (2013) Bilayer

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

8. Classification of lipid simplecompoundmiscel Fat, oil Wax Phospholipid Glycolipid Lipoprotein Sterol Terpene Icosanoid derivative Fatty acid Glycerol

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  Non- essential fatty acid  Plamatic, strearic acids  Essential fatty acid  Omega-3 fatty acid  linolenic acid  Eicosapentaenoic acid  Docosahesaenoic acid  Omega-6 fatty acid  linoleic acid  arachidonic acid Base on requirement

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

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
