The first PDF moments for three dynamical flavors in Baryon Chiral   Perturbation Theory
  We present a calculation of generalized baryon form factors in the framework of three-flavor covariant baryon chiral perturbation theory at leading one-loop order. This is needed for lattice calculations of the first moments of generalized parton distribution functions. The formulae we derive can be used to guide the chiral extrapolation of such lattice results.
