The implications of Chiral Quark Model with SU(3) and axial U(1) symmetry breakings as well as configuration mixing generated by one gluon exchange forces (χQMgcm) are discussed in context of proton flavor and spin structure as well as hyperon β-decay data. Apart from reproducing the success of χQM with symmetry breaking, it is able to improve upon the agreement with data in several cases such as, Gₐ/Gᵥ, Δ₈, <A₁ᵖ> dependent on spin polarization functions and (2 s/u+d), (2 s/ u+ d) and fₛ involving the quark distribution functions.
