title: Search for effect of longitudinally polarized protons on optically active amino acid.
abstract: As a test of the Vester-Ulbricht hypothesis that the specific optical activity of contemporary biology arose from a differential action of polarized nuclear particles, DL-leucine has been irradiated with protons of both positive and negative longitudinal polarization. Neither kind of protons caused by measurable decomposition difference in the two optical isomers of the amino acid.
