Which one among the following statements with regard to fatty acids is correct?
General ScienceNutrition
- AMost fatty acids have carboxyl group at one end and methyl group at the other end.
- BSaturated fatty acids carry even number of double bonds between carbon atoms.
- CSaturated fatty acids carry odd number of double bonds between carbon atoms.
- DMonounsaturated fatty acids carry as many hydrogen atoms as they can.
Explanation
Most fatty acids consist of a hydrocarbon chain with a carboxyl (-COOH) group at one end and a methyl (-CH3) group at the other, so statement A is correct. Saturated fatty acids have no double bonds at all, which rules out B and C. Monounsaturated fatty acids have one double bond and therefore cannot carry as many hydrogens as possible, ruling out D.
