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
