In this paper we examine the effects of electron Coulomb distortion on the second, fourth, and fifth structure functions and the left-right asymmetry (A_<LT>) for ^16O(e, e'p) reactions. For large incident electron energy the effects of the Coulomb distortion on the cross section are very small but have larger contribution on the structure functions. We obtain that the Coulomb effects are about 5%〜10% on the fourth and fifth structure functions and the left-right asymmetry in small missing momentum region. However, on the second structure functions, the effects are relatively small comparing with the fourth and fifth structure functions while they are bigger than the corresponding cross sections. In addition we compare our theoretical results with recently measured data from CEBAF.
