Abstract
As has been demonstrated in earlier communications, D,L-threo-β-phenylserine-3-14C and D,L-phenylalanine-3-14C are incorporated into the benzoyl moiety of urinary hippuric acid1,2. These results led to the assumption of an enzymatic, in vivo splitting between C2 and C3 of the side-chain, as has been found to occur in vitro for L-phenylserines3,4.
