The observation that Baryon number and Lepton number are conserved in nature provides strong motivation for associating gauge symmetries to these conserved numbers. This endeavor requires that the gauge group of electroweak interactions be extended from SU(2){sub L} X U(1){sub Y} to SU(2){sub L} X U(1){sub R} X U(1){sub Lepton} where U(1){sub R} couples only to the right-handed quarks and leptons. If it furthur postulated that right-handed currents exist on par with the left-handed ones, then the full electroweak symmetry is SU(2){sub L} X SU(2){sub R} X U(1){sub Baryon} X U(1){sub Lepton}. The SU(2){sub L} X SU(2){sub R} X U(1){sub Baryon} X U(1){sub Lepton} model is described in some detail. The triangle anomalies of the three families of quarks and leptons in the model are cancelled invoking leptoquark matter which is new fermionic matter that carries baryon as well as lepton numbers. In addition to the standard neutral boson (Z {degree}), the theory predicts two neutral gauge bosons with mass lower bounds of 120 GeV and 210 GeV which makes these particles prospective candidates for production at LEP, the TEVATRON and the SSC.
