4. A list of fatty acids is given below. The number of carbons each contains, as well as the number of double bonds, are listed right after the name. Rank the fatty acids 1-5 from highest melting point to lowest melting point. 1 - highest melting point, 5 - lowest melting point. Palmitic acid (16 carbons, 0 double bonds) Oleic acid (18 carbons, 1 double bond) Linolenic acid (18 carbons, 3 double bonds) Lauric acid (12 carbons, 0 double bonds)...
5) (3 pts) Draw an essential -6 fatty acid with 18 carbons and two cis double bonds. Number carbon atoms in this fatty acid starting at the carboxyl group. 6) (3 pts) Draw an essential 0-3 fatty acid with 18 carbons and three cis-double bonds. Number carbon atoms in this fatty acid starting at the carboxyl group. 7) (3 pts) Draw an unnatural trans-fatty acid arising from partial hydrogenation that contains 14 carbons and two double bonds, one of which...
