  The study of nuclear generalized parton distributions (GPDs) could be a
crucial achievement of hadronic physics since they open new ways to obtain new
information on the structure of bound nucleons, in particular, to access the
neutron GPDs. Here, the results of calculations of 3He GPDs in Impulse
Approximation are presented. The calculation of the sum of GPDs H + E, and
"tilde H", with the correct limits, will be shown. These quantities, at low
momentum transfer, are largely dominated by the neutron contribution so that
3He is an ideal target for these kind of studies. Nevertheless the extraction
of neutron information from future 3He data could be non trivial. A procedure,
which takes into account nuclear effects encoded in IA, is presented. The
calculation of H,E and "tilde H" allows also to evaluate the cross section
asymmetries for deeply virtual compton scattering at Jefferson Lab kinematics.
Thanks to these observations, DVCS off 3He could be an ideal process to access
the neutron information in the next future.
