Kinetic isotope effects (KIE) is defined as KIE=k[sub]H[/sub]/k[sub]D[/sub].
The theroretical maximum value of KIE is about 7 at room temperature for reactions where a bond to H or D is broken, hence the ability of deuteration to slow vital enzymic reactions significantly. Typical experimental values of between 1 and 2 are common.
If you consider the fact that the body goes to great lengths to maintain a constant temperature (which is a major factor in the rate of reactions), it becomes obvious why these apparently rather small changes in reaction rates can have dramatic effects.
I seem to recall reading that primary KIE’s had been observed of ca. 70, although I’m not sure what type of reaction this was from.
You folks are inspiring me to go to college. I love math, enjoyed chemistry, was offered a full ride to Harvey Mudd back in 1972, and decided to get married instead. (I’ll go back someday…)
Now I’m 47 and found myself feeling proud yesterday for figuring out a license plate: PB 2 AU.
Whoo-hoo!
Anyway, really interesting. Thanks!
