WebDec 15, 2024 · Kinetic parameters (K M, V max) for seven deuterated arachidonic acid derivatives were obtained. We showed that deuteration in the 13th position dramatically affects the kinetic parameters of the COX-2 and 15-LOX-2 enzymes, and deuteration in the seventh and 10th positions affects the operation of the 5-LOX enzyme, which opens up …
WebJun 15, 1987 · Even though 100 microM deuterated arachidonic acid results in 20-30 microM deuterated 5-HPETE, 80 microM exogenous 5-HPETE in the incubation could reduce the amount of deuterated LTA4 by only approx. 20%. The present study would thus indicate that the arachidonic acid moiety is preferentially converted to LTA4 in a …
