Why or why not?Explanation / Answer
1) Fatty acids are composed even numbers of carbon atom chains bonded with hydrogen atoms. Carboxyl group (-COOH) is present at one of the terminal ends of a fatty acid. The chain of carbon atoms can be as short as two atoms or longer. Fatty acids that have carbon–carbon double bonds are known as unsaturated fatty acids. Fatty acids without double bonds are known as saturated fatty acids.
