This compound and disparlure are both derivatives of fatty acids, molecules that featnre in many of the food problems people are so interested in now (and rightly so). Fatty acids in the diet are a popular preoccupation and the good and bad qualities of saturates, mo no unsaturates, and polyunsaturates are continually in the news. This too is organic chemistry. One of the latest molecules to be recognized as an anticancer agent in our diet is CLA (conjugated linoleic acid) in dairy products.

Polyunsaturated fatty acids, containing 4,5, or 6 double bonds and chain lengths of up to C36 are found in phosphatidylcholine of vertebrate retinas.121 Although the double bonds are rarely in conjugated positions in food fats and in animal bodies, some plants convert oleic or linoleic acid into fatty acids with as many as three or four conjugated double bonds.1213 Conjugated linoleic acid (9c, lit 18 2) can...
