Parton distribution functions (PDFs) are important to study the structure of the proton and hence the dynamics of quarks and gluons inside it. We study some of the PDFs from global CTEQ (Coordinated Theoretical-Experimental project on QCD) analysis in a wide range of momentum fraction x and different Q2 range. The numerical values of PDFs are taken from the LHAPDF library and the plots are obtained using APFEL.
