Within 48 h of administration of radiolabelled 10-formylfolate, folic acid and the polyglutamate derivative 10-formylfolate tetraglutamate to the rat, fragmentation products are found in the urine. The major catabolite was identified as p-acetamidobenzoate by chromatography and reverse isotope-dilution analysis.

Theoretical Accuracy

The accuracy of the least squares method in the isotope dilution analysis is studied using two models, viz a model of a two-parameter straight line and a model of a one-parameter straight line.The equations for the direct and the inverse isotope dilution methods are transformed into linear coordinates, and the intercept and slope of the two-parameter straight line and the slope of the one-parameter straight line are evaluated and treated.
