Figure 3

Membrane stability in presence of Mg2+ ions. Shows DLS measurements of C11 based membrane systems to determine the Mg2+ ion induced aggregate formation (crystalline aggregates and collapsed vesicles) concentration. The particle diameter (in nm) is plotted as a function of the added Mg2+ ion concentration. The vertical black dashed line indicates the Mg2+ ion induced aggregation formation concentration (Mg2+AIC). The ratio of fatty acid to its respective glycerol monoester and/or alcohol was maintained at 2:1. n = 3; error bars represent standard deviation (s.d.). UDA, undecylenic acid; UDG, glyceryl 1-undecylenate; UDOH, undecylenyl alcohol.
