英文摘要	Biochirality originates from the chiral influences in the universe. The parity non-conservation of weak neutral current, which takes place through the exchange of neutral boson Z(0) combined with the long range Coulomb interaction in atoms and molecules, produces a parity violating energy difference (PVED). In this note, the fact is to be indicated that there is a A-type second order phase transition of D- and L-alanine (valine) at a certain critical temperature T-C. The PVED is to be calculated as 6x10(-5) eV/molecule by varieties of modern physical and chemical methods including the differential scanning calorimeter (DSC), SQUID, single crystal X-ray diffraction spectra, low-temperature H-1-MAS ssNMR, Raman spectra and ultrasonic measurement. A mechanism that differs from Salam's hypotheses is also discussed here.; Multidisciplinary Sciences; SCI(E); 7; ARTICLE; 7; 603-608; 47
