[Study of potential-dependent changes in the conformation of the beta-carotene molecule using combination scattering spectroscopy].
It has been found by Raman spectroscopy that conformational changes of beta-carotene at liposomal membrane are potential-dependent. Changes of K+ or Ca+ gradient on the liposome membrane pressed the polyene chain of beta-carotene. A mechanism of potential-dependent carotenoid conformational changes in the regulation of "antenna" or "potential sensor" in biomembrane was discussed.
