WebThe lower melting point of oils is related to the higher degree of unsaturation. The presence of carbon to carbon double bonds in the oil molecules distorts the long fatty acid chains … WebThese are dominant in both animals and plants. Fatty acids with a single carbon bond are known as saturated fatty acids, and those with double bonds are termed unsaturated fatty acids. Saturated fatty acids range from the chain length of 12 to 24 carbon atoms. Further, foods such as cheese, butter, and pork are rich sources of saturated fatty ...
