There is evidence for existence of massless Dirac quasi-particles ingraphene, which satisfy Dirac equation in (1+2) dimensions near the so calledDirac points which lie at the corners at the graphene's brilluoin zone. Werevisit the derivation of Dirac equation in (1+2) dimensions obeyed byquasiparticles in graphene near the Dirac points. It is shown that parityoperator in (1+2) dimensions play an interesting role and can be used fordefining "conserved" currents resulting from the underlying Lagrangian forDirac quasi-particles in graphene which is shown to have U_{A}(1)*U_{B}(1)symmetry. Further the quantum field theory (QFT) of Coulomb interaction of 2Dgraphene is developed and applied to vacuum polarization and electron selfenergy and the renormalization of the effective coupling g of this interactionand Fermi velocity $v_{f}$ which has important implications in therenormalization group analysis of g and v_{f}.
