Geometric Isomerization of Unsaturated Fatty Acids in Solution

Geometric Isomerization of Unsaturated Fatty Acids in Solution 

The CTI of unsaturated fatty acid residues of a variety of L-a-phosphatidyl-cholines catalyzed by thiyl radicals were studied in alcoholic solutions. POPC (pal-mitoyl oleoyl PC), DOPC (dioleoyl PC), and SAPC (stearoyl arachidonoyl PC), to-

15 mmol Id of fatty acid contents with 7 mmol Id HOCH2CH2SH at 22 °C. Inset Time-courses of the formation of two mono-trans isomers 9-c/s,l 2-frans-Cl 8 2 and 9-trans,l 2-c/s-Cl 8 2. 

In particular, investigations should focus on the erythrocyte membrane phospholipids, which are the preferential storage place for arachidonic acid after biosynthesis. As shown in a previous section, nutritional investigations indicated that trans fatty adds are incorporated in cell membranes because the trans dietary pre-
