Stoffwechsel von Phosphoglyceriden, Sphingolipiden und Cholesterin

  • G. Löffler
Chapter
Part of the Springer-Lehrbuch book series (SLB)

Zusammenfassung

Eine entscheidende Funktion der Lipide ist der Aufbau sämtlicher zellulärer Membranen, womit erst die Existenz von Zellen, deren Inneres gegen die Außenwelt abgeschirmt ist, ermöglicht wird. Für diese Funktion sind amphiphile Lipide wie Phospholipide und Sphingolipide besonders geeignet, die neben den für Lipide typischen hydrophoben Alkanketten auch über hydrophile, polare und geladene Gruppen verfügen und somit die für alle zellulären Membranen typischen Doppelschichten ausbilden können. Auch Cholesterin ist ein essentieller Bestandteil aller tierischer Membranen.
