      (a) galactose, fructose or xylose labelled with 13 C at least at one specific position, or a starch composed of glucose units labelled with 13 C at least at one specific position;
      (b) an amino acid labelled with ''C at least at one specific position;
      (c) lactic acid or citric acid labelled with 13 C at least at one specific position;
      (d) a fatty acid labelled with 13 C at least at one specific position;
      (e) a glyceride labelled with 13 C at least at one specific position;
      (f) glycerol labelled with 13 C at least at one specific position; and
      (g) aminopyrin of which the dimethylamino group at position 4 is labelled with 13 C, phenacetin of which the ethoxy group is labelled with 13 C at position 1, or methacetin of which the methoxy group is labelled with 13 C.

    • It is an object of the present invention to provide in vivo analytical methods that allow for diagnosis and management of therapy for diseases involving discrete biochemical pathways. In the method of the invention, a labelled tracer probe, a specifically designed substrate of a 'gateway' enzyme, an enzyme marking a regulatory point in a discrete biochemical pathway, is administered to a subject; a labelled product of the action of the enzyme is measured; and the appearance and concentration of the product are related to the disease condition of interest. Determination of the rate of substrate-product conversion of the gateway enzyme allows for the analysis to be made. The method involves administering a defined amount of a labelled 'metaprobe' substrate of the gateway enzyme to a subject, at a site that provides access to a desired pool of the gateway enzyme in the subject, and measuring the amount of the chosen labelled product. The presence and amount of the chosen labelled product in, e.g., the breath, definitely indicates that the labelled metaprobe has been metabolized by the specific enzyme in the specific biochemical pathway under consideration, and from the calculated rate of substrate-product conversion by the gateway enzyme, the desired diagnostic determination may be made. Likewise, if a specific therapeutic treatment for a disease is underway with a patient, this method allows for a minimally invasive assessment of the effectiveness of the treatment, with minimal discomfort to the patient.
