  2. Amphiphile - Wikipedia

    en.wikipedia.org/wiki/Amphiphile

    Phospholipids, a class of amphiphilic molecules, are the main components of biological membranes. The amphiphilic nature of these molecules defines the way in which they form membranes. They arrange themselves into lipid bilayers, by forming a sheet composed of two layers of lipids. Each layer forms by positioning their lypophilic chains to the ...

  3. Ethanol-induced non-lamellar phases in phospholipids - Wikipedia

    en.wikipedia.org/wiki/Ethanol-induced_non...

    There are various usages of ethanol which include an additive to gasoline, a primary ingredient for food preservation as well as alcoholic beverages and being used for transdermal drug delivery. For example, it can function as an antiseptic in topical creams to kill bacteria by denaturing proteins. Ethanol is an amphiphilic molecule meaning ...

  4. Glycerophospholipid - Wikipedia

    en.wikipedia.org/wiki/Glycerophospholipid

    Glycerophospholipids are the main structural component of biological membranes. Their amphipathic nature drives the formation of the lipid bilayer structure of membranes. The cell membrane seen under the electron microscope consists of two identifiable layers, or "leaflets", each of which is made up of an ordered row of glycerophospholipid ...

  5. Phospholipid - Wikipedia

    en.wikipedia.org/wiki/Phospholipid

    The phosphate group can be modified with simple organic molecules such as choline, ethanolamine or serine. [citation needed] Phospholipids are a key component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic.

  6. Micelle - Wikipedia

    en.wikipedia.org/wiki/Micelle

    A micelle (/ m aɪ ˈ s ɛ l /) or micella (/ m aɪ ˈ s ɛ l ə /) (pl. micelles or micellae, respectively) is an aggregate (or supramolecular assembly) of surfactant amphipathic lipid molecules dispersed in a liquid, forming a colloidal suspension (also known as associated colloidal system). [4]

  7. Lecithin - Wikipedia

    en.wikipedia.org/wiki/Lecithin

    Lecithin (/ ˈ l ɛ s ɪ θ ɪ n / LESS-ith-in; from the Ancient Greek λέκιθος lékithos "yolk") is a generic term to designate any group of yellow-brownish fatty substances occurring in animal and plant tissues which are amphiphilic – they attract both water and fatty substances (and so are both hydrophilic and lipophilic), and are ...

  8. Amphoterism - Wikipedia

    en.wikipedia.org/wiki/Amphoterism

    In organic chemistry and biochemistry, important examples include amino acids and derivatives of citric acid. Although an amphiprotic species must be amphoteric, the converse is not true. For example, a metal oxide such as zinc oxide, ZnO, contains no hydrogen and so cannot donate a proton. Nevertheless, it can act as an acid by reacting with ...

  9. Apolipoprotein - Wikipedia

    en.wikipedia.org/wiki/Apolipoprotein

    The lipid components of lipoproteins are insoluble in water. However, because of their detergent-like (amphipathic) properties, apolipoproteins and other amphipathic molecules (such as phospholipids) can surround the lipids, creating a lipoprotein particle that is itself water-soluble, and can thus be carried through body fluids (i.e., blood ...
