Fatty acids are water insoluble long chain hydrocarbons with one carboxyl group. Fatty acid chains may be of following two types : saturated fatty acids and unsaturated fatty acids. Saturated fatty acids do not possess any double bond in their hydrocarbon chain. Unsaturated fatty acid possess one or more double bonds in their hydrocarbon chain. Option C is the correct answer - Polyunsaturated fats have lower melting point than monounsaturated fatty acids. Reason : Monounsaturated fatty acids have high melting point than polyunsaturated fatty acids hence these are liquids at room temperature and semi solids or solids when refrigerated. Example - oliec acid and palmitoleic acid. Polyunsaturated fats have lower melting point than monounsaturated fats hence, they have a liquid consistency at room temperature. Examples - omega-3 and omega - 6 fatty acids. Hence, option C is the true statement. Both Polyunsaturated and monounsaturated fatty acids functions are similar- they store energy, helps in skin barrier maintenance, skin cell proliferation, hormone production etc.
