Oils and Fats

General objective of this lecture is to present on Oils and Fats. Here briefly present on Chemical structure of Oils and fats – important for storing chemical energy in living things. All fats and oils are a mixture of saturated fatty acids and unsaturated fatty acids. Unsaturated fatty acids include monounsaturated and polyunsaturated fats. Finally discuss on how Fatty acids present in mixture affect the properties; Saturated triglycerides pack closely together and Attractive forces – higher melting point.
