Which of the following vegetable oils does not contain essential fatty acids?
(1) Sunflower oil
(2) Mustard oil
(3) Coconut oil
(4)Groundnut oil
Answer: (1) Fatty Acids are aliphatic carboxylic acid with varying hydrocarbon lengths at one end of the chain joined to the terminal carboxyl (-COOH) group at the other end. The general formula is R-(CH2)n-COOH. Fatty acids are predominantly unbranched, and those with even numbers of carbon atoms between 12 and 22 carbons long react with glycerol to form lipids (fat-soluble components of living cells) in plants, animals, and microorganisms. Sunflower oil is high in essential vitamin E and has no essential saturated fat.
