Abstract
We present selected recent results on the nucleon structure using lattice QCD simulations with physical or close to physical pion masses. Results include, the nucleon axial charge, tensor charge, \(\sigma \)-terms, average momentum fraction and the decomposition of the nucleon spin. Results about the proton electric form factors are also discussed.
