  We analyze the moments of the isosinglet generalized parton distributions H,
E, H-tilde, E-tilde of the nucleon in one-loop order of heavy-baryon chiral
perturbation theory. We discuss in detail the construction of the operators in
the effective theory that are required to obtain all corrections to a given
order in the chiral power counting. The results will serve to improve the
extrapolation of lattice results to the chiral limit.
