In this work, using the Laplace transformation technique we present our results for non-singlet quark distributions as well as nucleon structure function F2(x, Q2) in unpolarized case at next-to-next-to-leading order QCD accuracy. We shall particularly compare our
results for the sets of valence-quark parton distribution functions with the contemporary collaborations
like CT14, CT18, MMHT14, MKAM16 and NNPDF. To construct the nucleon
structure function, we employ the expansion of Jacobi polynomials which is a suitable transform
to convert the results of non-singlet structure function from the Laplace s-space to
Bjorken x-space. We shall also consider the contributions of target mass correction as well as the higher twist effects at large-x region for the proton and deuteron structure functions. Our results for the unpolarized quark distribution functions and nucleon structure functions are in good agreement with recent theoretical models and available experimental data.
