Flavor chirality is combined with genuine left-right symmetry in a unified SU(5)LSU(5)R manner. An SU(2)LSU(2)R-singlet fermionic companion to each quark and lepton is predicted; the associated seesaw mechanism is examined in the light of proton stability. The evolution of sin2θW exhibits distinctive features: (i) It starts at (3/16 and rises, and (ii) it is N dependent (N being the total number of generations). N=3,4 dictates an intermediate mass scale ∼107 GeV, marking the breakdown of SU(5)R.
