    11S(12R)-EET

    		Others Others
    11S(12R)-EET is a dominant enantiomer of epoxytrienoic acid (EET) that is metabolized at a higher rate in rat organs. It shows enantiomeric-dependent reaction selectivity in hydration, especially in the case of 11,12-EET, where water addition is non-regioselective, while in 8,9-EET, water addition occurs mainly at the C9 position. In addition, 11S(12R)-EET generates diol products with specific stereochemistry through enzymatic hydration reactions, which are affected by the selective recognition of epoxidases, reaction conversion rates, and substrate binding parameters .

    11R(12S)-EET

    		Others Others
    11R(12S)-EET is a cis-epoxytrienoic acid (EETs) derivative that is metabolized by cytoplasmic cyclooxygenases. Studies have shown that 14(R), 15(S)-, 11(S),12(R)-, and 8(S),9(R)-EETs are metabolized at significantly higher rates than their enantiomers. Enzyme-catalyzed hydration revealed that water addition was non-regioselective for the 11,12-EET enantiomers, whereas water addition occurred primarily at the C9 position for both enantiomers of 8,9-EET. These results suggest that the metabolic properties of 11R(12S)-EET and other EET enantiomers in enzyme-catalyzed processes are significantly affected by their stereostructures .
