"The use of enzymes as catalysts is gaining widespread use due to the need to move into green chemistry approaches. This has been fostered also by the discovery that enzymes can function in novel environments such as environmental extremes and organic solvents. In this work, soybean oil was used as the raw material to synthesize a dicarboxylic acid, which was then polymerized to get polyester. A commercially available lipoxygenase was used to form a conjugated hydroperoxide at carbon thirteen from the free fatty acids obtained from soybean oil hydrolysis. This reaction was followed by a reaction with hydroperoxide lyase derived from tomato leaves, thereby forming the 12-oxo-dodeceneoic acid and a 6-carbon aldehyde. Traumatic acid, a 12 carbon dicarboxylic acid, was formed by oxidation of 12-oxo-dodeceneoic acid. The traumatic acid thus formed was enzymatically polymerized using Novozym 435-Lipase CA to obtain the polyester. The products of each reaction were analyzed by Gas Chromatography/ Liquid Chromatography combined with Mass Spectroscopy. Gel Permeation Chromatography was used to confirm the molecular weight of the polyester"--Abstract, page iii.
