Carrying out x-ray absorption spectroscopic experiments at 10K, the authors have examined the question of the state of vanadium as it exists both in intact ascidian blood cells and in freshly lysed blood cells. Both high energy- resolution vanadium K-edge and EXAFS (X-ray absorption fine structure) spectra have been acquired and are evaluated in detail. The question of the "in vivo" ligation of vanadium is specifically addressed. The results of comparisons of blood cell vanadium with vanadium in structurally known chelating environments consistent with proposed biological models are also given.
