Detection of aluminium(III) binding to citrate in human blood plasma by proton nuclear magnetic resonance spectroscopy.
Reactions of Al3+ (50-500 mumol l-1) with intact blood plasma and its low relative molecular mass ultrafiltrate (< 5 kDa) have been studied by proton nuclear magnetic resonance spectroscopy. Binding to citrate was detected and was reversed by addition of desferrioxamine. The use of combined exponential and sine-bell functions for the resolution enhancement of spectra of plasma is illustrated.
