The Lipids (Eg: fats and oils) are the esters of moderate to long chain fatty acids, they are hydrophobic in nature. The monomers of lipids are glycerol and fatty acids. They are of two types as described below.
1. Saturated fats
2. Unsaturated fats
There are no double bonds or triple bonds in saturated fatty acids whereas unsaturation (presence of either double or triple bonds) is higher in unsaturated fatty acids.
Thus, the options (a), (d) and (b) are incorrect.
There are no double bonds or triple bonds in saturated fatty acids whereas unsaturation (presence of either double or triple bonds) is higher in unsaturated fatty acids.
Therefore, the correct option is – c. saturated fats and unsaturated fats.
