Göttinger Wissenschaftler beobachten Bewegung von Lipidmolekülen durch Röntgenpulse

(PresseBox) (Göttingen, )
Wissenschaftler der Universitäten Göttingen und Augsburg sowie des Hamburger Forschungsinstituts DESY haben eine neue Methode entwickelt, um die Bewegung von Lipidmolekülen zu beobachten. Die Forscher "rüttelten" mit kurzen Röntgenpulsen von außen an einem Stapel von Lipidmembranen. Dabei konnten sie erkennen, dass sich die Membranen durch die akustischen Wellen auf und ab bewegten und ihre innere Struktur zu schwingen begann. Die Ergebnisse wurden in der Fachzeitschrift Physical Review Letters veröffentlicht.

Biomoleküle sind sehr beweglich: Unter dem Einfluss von Wärme schwingen, drehen und strecken sie sich. Da sich diese Bewegungen allerdings ständig überlagern, lassen sie sich experimentell nur gemittelt erfassen.
