The flavor SU(3)f group symmetry of QCD is systematically considered as the heavy c quark limit of SU(4)f. Within that scheme we argue that the U(1)A anomaly prevents Gell-Mann's choice for the realization of the su(4)f [and thereby the su(3)f] algebra for the particular case of the neutral axial currents. Rather, Weyl's choice for the SU(4)f generators has to be used which leads to a neutral strong axial vector current having the same structure (up to a constant factor) as the weak one.
