Lipids and Fatty Acids

 

  • Different fatty acids have different length, degree of unsaturation (number of double bonds) and properties such as melting point, fluidity etc. 
  • The length of the fatty acids determines their melting point. As the length increases, the melting point increases.
  • Fatty acids are amphipathic molecules, that is, they have both hydrophilic (carboxylic acid) and hydrophobic (hydrocarbon) component.
  • But they are largely non-polar (hydrophobic) due to large hydrocarbon chains. 
  • If there are only single bonds between neighbouring carbons in the hydrocarbon chain, the fatty acid is said to be saturated.

 

 

 

When the hydrocarbon chain contains a double bond, the fatty acid is said to be unsaturated. For example, Oleic acid.
