摘要：

A set of chemical reactions is proposed to account for the formation of pyridoxal phosphate, Vitamin B-6, from a primeval atmosphere composed of cyanoacetylene, diacetylene, carbon monoxide, hydrogen, water, and a phosphoric acid. The reactions have been shown to be feasible from the overall enthalpy changes in the ZKE approximation at the HF and MP2/6-31G* level. (c) 2006 Elsevier B.V. All rights reserved.
