First, menaquinone-2 and ubiquinone-2 were synthesized then using 1H-1H 2D NOESY and ROESY NMR spectroscopy, we demonstrated that both molecules adopt a folded, U-shaped conformation in solution and within a model membrane interface. These folded conformations are in stark contrast to the extended conformations seen in literature. Folded conformations likely affect reactivity, function, and recognition within the ETS and provide insight into drug development of potent inhibitors.born digitalStudent workspostersengCopyright and other restrictions may apply.
