Lipids consist of long chains of carbon, hydrogen and oxygen called fatty acids.
Depending upon the number and type of bonds between carbon atoms, fatty acids are of two types:
Saturated fatty acidsonly contain single bonds between carbon atoms. This indicates that they contain the highest number of hydrogen atoms possible i.e. 14. Saturated fatty acids are predominantly found in fats.
Unsaturated fatty acids contain double and triple bonds between carbon atoms and contain relatively less hydrogen atoms. Unsaturated fatty acids are found in oils.
