Lipid bilayer — [ phosphatidylcholine.] A lipid bilayer or bilayer lipid membrane (BLM) is a membrane composed of lipid molecules (usually phospholipids). The lipid bilayer is a critical component of all biological membranes, including cell membranes, and so is… … Wikipedia
Lipid raft — organisation, region (1) is standard lipid bilayer, while region (2) is a lipid raft. The plasma membrane of cells is made of a combination of glycosphingolipids and protein receptors organized in glycolipoprotein microdomains termed lipid… … Wikipedia

Membrane transport — In cellular biology the term membrane transport refers to the collection of mechanisms that regulate the passage of solutes such as ions and small molecules through biological membranes namely lipid bilayers that contain proteins embedded in them … Wikipedia
Model lipid bilayer — A model lipid bilayer is any bilayer assembled in vitro, as opposed to the bilayer of natural cell membranes or covering various sub cellular structures like the nucleus. A model bilayer can be made with either synthetic or natural lipids. The… … Wikipedia
Membrane curvature — is the geometrical measure or characterization of the curvature of membranes. The membranes can be naturally occurring or man made (synthetic). An example of naturally occurring membrane is the lipid bilayer of cells, also known as cellular… … Wikipedia
Membrane contact site — Membrane contact sites are areas within a cell where the membranes of two organelles are arranged in close proximity (not to be confused with cell junctions between the cells). These sites are thought to be important in the transport of small… … Wikipedia

БЛМ служит барьером и поддерживает неравновесную концентрацию веществ в цитоплазме. Схема структуры плазматической мембраны. Мембрана содержит сильно связанные собственные (интегральные) белки, которые пронизывают двойной липидный слой и слабо связанные белки на внешней стороне. Также присутствуют включения холестерина и сахарозные цепи белков на поверхности
