Spectral deconvolution was used in the crowded orthophosphate-monoester region to partition signal into the following components: (i) orthophosphate; (;/) humic P, identified as a broad feature centred at 4.8 ppm; (Hi) phytate (myo-inositol hexakisphosphate); (fv) the phytate isomer scyllo-inositol hexakisphosphate (referred to hereon as scyllo-[IP.sub.6]); (v) lipid P, identified as the sum of [alpha]- and [beta]-glycerophosphate, the alkaline hydrolysis products of phospholipid; and (vi) RNA P, identified as the sum of up to 4 peaks assigned to mononucleotides derived from alkaline hydrolysis of RNA.
