We present results on the disconnected contributions to three point functions entering in studies of hadron structure. We use Nf = 2+1+1 twisted mass fermions and give a detailed description on the results of the nucleon sigma-terms, isoscalar axial charge and first moments of bare parton distributions for a range of pions masses. In addition we give the s-terms and the computations are performed using QUDA code implemented on GPUS.
