The cell membrane (Membrana cellularis, cytomembrane) or peanale (lat. membrane), also called plasma membrane in plant cells, is a biomembrane that surrounds the living cell and maintains its inner environment. At a thickness of about 6-10 nm, it can be detected by light microscopy only as a vague line. Each cell identifies itself externally by means of its peripheral proteins (see [[antigen]]). These membrane proteins lie or ″schwimmen″ on or in the membrane. In addition, short-chain, partly tree-like branched carbohydrate compounds are often attached to the proteins and lipids on the outside of the cell membrane for labelling purposes. This is referred to as glycoproteins or glycolipids. The external structures of the cell membrane often have a receptor function. These glycoproteins and glycolipids also form glycocalyx, which provides stability in cells without cell walls. The outer side of the cell membrane is occupied by different receptors.

Nachricht im Original (Zellmembran)
Die Zellmembran (Membrana cellularis, Zytomembran) oder Peanale (lat. Häutchen), bei Pflanzenzellen auch Plasmalemma genannt, ist eine Biomembran, die die lebende Zelle umgibt und ihr inneres Milieu aufrecht erhält. Bei einer Stärke von etwa 6–10 nm ist sie lichtmikroskopisch höchstens als vage Linie erfassbar. Jede Zelle identifiziert sich mit Hilfe ihrer peripheren Proteine nach außen hin (siehe [[Antigen]]). Diese Membranproteine liegen oder ″schwimmen″ auf oder in der Membran. Zusätzlich dazu hängen zur Markierung an der Außenseite der Zellmembran oft kurzkettige, teilweise bäumchenartig verzweigte Kohlenhydratverbindungen an den Proteinen und an den Lipiden. Man spricht dann von Glykoproteinen bzw. Glykolipiden. Die nach außen ragenden Strukturen der Zellmembran haben vielfach Rezeptor-Funktion. Diese Glykoproteine und Glykolipide bilden auch die Glykokalyx, die bei Zellen ohne Zellwand für Stabilität sorgt. Die Außenseite der Zellmembran ist mit verschiedenen Rezeptoren besetzt.
