Abstract
We discuss the influence of glueball coupling to nucleons on the weak axial-vector coupling constants including the singlet channel. We cons ider the possibility of the introduction of a constituent gluon contri bution to the proton spin. The estimated value for this quantity seems to be rather small for moderate values of glueball nucleon coupling.
