The presence of unsaturation in fatty acids, referring to the existence of double bonds between carbon atoms in the hydrocarbon chain, can be detected through various physical and chemical methods. One common method involves the reaction of unsaturated fatty acids with bromine or iodine, known as bromination or iodination, respectively. Unsaturated bonds react with these halogens, resulting in the formation of colorless compounds and a decrease in the intensity of the color of the bromine or iodine solution, thus indicating the degree of
