Lipids and Fatty Acids
Characteristics of Lipids
NonpolarLargely 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.
Characteristics of Lipids
Lipids (lipid) are organic compound composed of carbon, hydrogen, oxygen, essentially.
Classification of lipid
simple compound miscel
Fat, oil
Wax

Lipoprotein
Sterol
Terpene
Icosanoid
derivative
Fatty acid
Glycerol
Characteristics of fatty acid
Consisted of carboxyl and hydrocarbon
