Isovaline (I) is of considerable interest cosmologically in that (1) it is one of the twelve non-protein amino acids which have been isolated from the Murchison meteorite\* and (2) unlike the other chiral amino acids in this meteorite, it has no ahydrogen at its asymmetric center and hence cannot ra

[14C] DL-phenylalanine and [35S]DL-methionine were resolved using cellulose column chromatography. The assignment for the resolved enantiomers was carried out by means of co-chromatography with non-labeled oL-amino acids after modification with fluorodinitrobenzene. The optical purity of the enanti
