|Generalized parton distributions (GPDs) describe the
internal structure of hadrons in terms of quark and gluon
degrees of freedom, combining the information mediated by
form factors, parton densities and distribution amplitudes.
In this talk I present results from full lattice QCD for
the lower moments of GPDs, from which images of the
spatial distribution of charge and spin in the fast moving
nucleon are derived.
