반응 단계

The bioconversion of 1,2-hexadecanediol was tested following the procedures set forth in Example 24. This substrate was tested to demonstrate the ability to form a (ω,ω-1)-dihydroxy fatty acid. Recovery was 0.138 g from 0.253 g starting material (54.5% recovery). NMR shows the 1,2-diol to be unchanged, as expected from olefin studies. But, interestingly, CH3 oxidation to the 15,16-dihydroxyhexadecanoic acid was lower than seen with octadecene, because the starting material was solid. Conversion was only about 30%. Some fatty unsaturation and minor polypropylene glycol were also seen. Since the NMR results were fairly convincing, no GC/MS analysis was performed.
