Abstract: The nucleon distribution amplitudes and the nucleon-to-pion transitiondistribution amplitudes are investigated at leading twist within the frame of alight-cone quark model. The distribution amplitudes probe the three-quarkcomponent of the nucleon light-cone wave function, while higher ordercomponents in the Fock-space expansion of the nucleon state are essential todescribe the nucleon-to-pion transition distribution amplitudes. Adopting ameson-cloud model of the nucleon the nucleon-to-pion transition distributionamplitudes are calculated for the first time.
