In the following article a QCD analysis of proton structure function Fp2 (x,Q2) is presented. A wide range of the inclusive neutral-current deep- nelastic-scattering (NC DIS) data used in order to extract the updated set of parton distribution functions (PDFs). The HERA "combined" data set on Qr,NC together with all available published up to date data for heavy quarks Fc,b 2 (x,Q2), longitudinal FL(x,Q2) and also very recent reduced DIS cross sections Qr,NC(x,Q2) data from HERA experiments are the input in the present next-to-leading order (NLO) QCD analysis which determines a new set of parton distributions, called KKT11C. The extracted PDFs in "fixed flavour number scheme" (FFNS) are in very good agreement with the available theoretical models
