We present BeppoSAX observations of three gamma-ray emitting quasars, namely 0836+710, 1510-089 and 2230+114. The three objects have been detected up to 100 keV showing extremely flat power-law spectra above 2 keV (energy index alpha_{2-10}=0.3-0.5). The soft X-ray spectrum of 0836+710 implies either an absorption column density higher than the galactic one or an intrinsically very hard slope (alpha_{0.1-1}=-0.2) below 1 keV. 1510-089 shows a soft excess, with the low energy spectrum steeper (alpha_{0.1-1}=1.6) than the high energy power-law. The results are discussed in the framework of current Inverse Compton models for the high energy emission of Flat Spectrum Radio Quasars and are used to estimate the physical quantities in the jet emitting region and to shed light on the energy transport mechanisms in jets. Finally we discuss the estimates of the jet luminosity in the context of the Blandford & Znajek mechanism for jet production.
