Abstract
Sum of the time component of term and the induced pseudo scalar term in axial current is shown to be the t-channel pion pole in Born terms for pion electroproduction near threshold. We also show that this term represents the charged pseudo scalar quark density matrix elements in nucleon and manifests itself in the amplitude on this reaction.
