Webthe pion structure allows the determination of parton distributions in kaons. In addition, we show that the intrinsic (low Q2) sea of pions and kaons are di erent due to their di erent valence quark structure. Finally, we analize the feasibility of a method to extract kaon’s parton distribution functions within
