The micro gold electrode modified by thiol layer was used as a working electrode in the cyclic voltammetry method. This analytical system was used for determining the neutral smell compounds: geraniol and coumarin. The decrease in reduction current value of [Fe(CN)6]-3 ions was observed already at the concentration of 10-5 M of the compound investigated. The dimensions of these changes were different for each compound and their discrimination by the above sensor was possible.

The hemolymph juvenile hormone binding protein (JHBP) from Galleria mellonella contains two disulphide bridges/molecule and no free Cys residues. An alignment of primary structures of other Lepidopteran JHBPs indicates that Cys residues, equivalent to Cys10,17,151,195 in G. mellonella JHBP, may be involved in -S-S- bridge formation.
