METHOD OF FAT-RESORPTION DETERMINATION, AS WELL AS SUBSTANCES EMPLOYED FOR THIS AND PREPARATIONS DERIVED THEREFROM

摘要

The invention relates to a method of determining the fat resorption, in which a radio-active test fat and reference substance are orally administered. According to the present invention a triether of glycerol of which one or more oxygen atoms are substituted by atoms of the isotope 75Se or 123mTe, is used as a reference substance. In a preferred embodiment use is made of 125I- or 131I-triolein as test fat. The proposed reference substances are novel compounds. A suitable reference substance is for example l-butylselenyl-75-Se-2,3-dioctadecyloxy-propane.
