Low Molecular Mass (LMM-SH) complexes of cysteine and/or glutathione with electrophile forms of mercury (E⁺Hg, i.e., MeHg⁺; EtHg⁺ or Hg²⁺). The formation of the LMM-S-E⁺Hg complexes depicted here is of crucial importance for the preferential distribution of E⁺Hg forms to their target organs (Zalups 2000; Bridges and Zalups 2005, 2010, 2017; Farina et al. 2011a,b). The distribution of EtHg⁺-S-complexes has been rarely studied in the literature (Dórea et al. 2013).
