There's 15N, 39K, 19F, and also 13C, |
But of all the atoms East to West, the nucleus I like best is 31P.|
Proton spins are everywhere, and MRIs reveal their density.|
But all that leaves me unimpressed; the nucleus I like best is
31P. |
Take a limb, get it shimmed, and sample from the muscles that you see.|
A spectrum lets you quantify the PCr, Pi, and ATP.|
Cell pH can be deduced from the inorganic phosphate frequency; |
You can likewise measure magnesium using the chemical shift of
ATP. |
If you scan a leg or hand during stimulation and recovery, |
The spectra let you find the rates of using and creating ATP. |
Now NMR can take you far beyond this type of phosphate chemistry, |
But I've come clean and I've confessed -- the nucleus I like best is 31P.
