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.
