Flavor chirality is combined with genuine left-right symmetry in a unified SU(5)/sub L/xSU(5)/sub R/ manner. An SU(2)/sub L/xSU(2)/sub 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 sin/sup 2/theta/sub W/ 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 --10/sup 7/ GeV, marking the breakdown of SU(5)/sub R/.
