## Abstract Apparent diffusion coefficients (__D__^a^) of individual metabolites can be studied __in vivo__ by diffusion NMR spectroscopy using an echo sequence sensitized to molecular motion. The methods are based on the echo attenuation due to phase dispersion resulting from incoherent displaceme

A technique to determine absolute metabolite concentrations of the kidney in vivo using 31P NMR is described. The technique is based on the use of methylphosphonic acid (MPA), which gives rise to a well-resolved peak upfield from in vivo phosphorous metabolite resonances, as an "internal standard."
The difference in concentration of phosphorylated metabolites in muscles with different fiber composition was studied in vivo by localized 31P nuclear magnetic resonance spectroscopy in the rat hindlimb. 120-160 pl volumes were selected in regions containing the soleus and gastrocnemius muscles. Con
In vivo 31P NMR spectra of wheat, soybean and mustard seeds were recorded during ripening. Signals were detected from phosphomonoesters, cytoplasmic and vacuolar inorganic phosphate phytate, nucleoside tri- ), phosphate (NTP) and nucleoside diphosphosugars. The spectra of extracts showed an accumul
