  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 ($\chi$QM$_{gcm}$) are discussed in context of proton flavor and spin
structure as well as hyperon $\beta$-decay data. Apart from reproducing the
success of $\chi$QM with symmetry breaking, it is able to improve upon the
agreement with data in several cases such as, $G_A/G_V, \Delta_8, <A_1^p>$
dependent on spin polarization functions and ($\frac{2 \bar s}{u+d}$),
($\frac{2 \bar s}{\bar u+\bar d}$) and f_s involving the quark distribution
functions.
