## o-Hydro~y-DL-phenylalanine-2-~~C was prepared by the condensation of o-methoxybenzyl chloride and ethyl acetamidocyano-~c e t a t e -2 -~~C and subsequent hydrolysis. The rucemute was resolved by the stereospecijic action of chymotrypsin on the amino acid ethyl ester at pH 5.0 to give the two i
[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
