Various new nucleosides bearing one or two lipophilic groups at the 2′-position have been synthesized. The lipophilic substituents were attached to a 2′-hydroxy, 2′-amino, or 2′-thio function. These lipophilic nucleosidesanchor in large unilamellar POPC vesicles serving as phospholipidmembrane models. The insertion of these molecules into the membranes was investigated by NMR techniques.

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 or glycerol of which one or more oxygen atoms are substituted by atoms of the isotope .sup.75 Se or .sup.123m Te, is used as a reference substance. In a preferred embodiment use is made of .sup.125 I- or .sup.131 I-triolein as test fat. The proposed reference substances are novel compounds. A suitable reference substance is for example 1-butylselenyl-.sup.75 -Se-2,3-dioctadecyloxypropane.

A number of positively charged lipids containing pyridinium, N-methylmorpholinium, N-methylimidazolinium, 4-N,N-dimethylaminopyridinium, and 4-N,N-dimethylcyclohexylammonium groups linked directly to the C(3) atom of 1,2-di-O-alkylglycerols with Br-, MsO-, and TsO- anions as counterions were synthesized.
