We use the constituent quark model to extract polarized parton distributions and finally polarized
nucleon structure function. Due to limited experimental data which do not cover whole (x,Q2) plane and
to increase the reliability of the fitting, we employ the Jacobi orthogonal polynomials expansion. It will be
possible to extract the polarized structure functions for Helium, using the convolution of the nucleon polarized
structure functions with the light cone moment distribution. The results are in good agreement with available
experimental data and some theoretical models
