We discuss quark distribution amplitudes for the nucleon obtained from perturbative QCD in connection with QCD sum rules on the light cone. Because of nonperturbative contributions these amplitudes have a complex nonsmooth structure and are dominated by strong correlations at the edges of the phase space. The antisymmetric part of the mixed symmetry amplitudes is found to be enhanced.
