Figure 2

Linear alkyl polyamines putrescine (Put), spermidine (Spd), spermine (Spm), and bis(ethyl)spermine (BESpm)—all-trans conformations, in their totally protonated form (physiological species). (The represented structures correspond to optimised geometries, calculated with dedicated theoretical methods, at the Density Functional Theory level).
