Witryna11 kwi 2024 · This effect is observed when comparing the inhibition of COMT (Fig. 3) by ACN (9) and NACN (10), which suggests that NACN binds tightly and is a poor substrate. These data illustrate, however, that a lower pKa is not the only factor involved in inhibiting COMT as NDA (7) is not as strong of an inhibitor as NACN (10) despite a … WitrynaQ.28 Fluoro acetic acid is stronger than chloro acetic acid.
