  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. 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 ...

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

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

    Ethanol is an amphiphilic molecule meaning that it has chemical and physical properties associated with hydrophobic and hydrophilic molecules. [ 3 ] [ 4 ] Although, studies show that when penetrating through the biomembrane its hydrophobic abilities appear to be limited based on its preference to bind closely to the hydrophilic region of the ...

  5. Membrane lipid - Wikipedia

    en.wikipedia.org/wiki/Membrane_lipid

    Lipids are amphiphilic: they have one end that is soluble in water ('polar') and an ending that is soluble in fat ('nonpolar'). By forming a double layer with the polar ends pointing outwards and the nonpolar ends pointing inwards membrane lipids can form a 'lipid bilayer' which keeps the watery interior of the cell separate from the watery ...

  6. Phosphatidylinositol - Wikipedia

    en.wikipedia.org/wiki/Phosphatidylinositol

    The biomolecule can exist in 9 different isomers. It is a lipid which contains a phosphate group, two fatty acid chains, and one inositol sugar molecule. Typically, the phosphate group has a negative charge (at physiological pH values). As a result, the molecule is amphiphilic. The production of the molecule is limited to the endoplasmic reticulum.

  7. List of naturally occurring phenethylamines - Wikipedia

    en.wikipedia.org/wiki/List_of_naturally...

    Naturally occurring phenethylamines are organic compounds which may be thought of as being derived from phenethylamine itself that are found in living organisms. Tyramine is a phenethylamine that occurs widely in plants [ 1 ] and animals , and is metabolized by various enzymes , including monoamine oxidases .

  8. Micelle - Wikipedia

    en.wikipedia.org/wiki/Micelle

    An amphiphilic behavior can be observed for water and an organic solvent or between two organic solvents. Note 2 Polymeric micelles have a much lower critical micellar concentration (CMC) than soap (0.0001 to 0.001 mol/L) or surfactant micelles, but are nevertheless at equilibrium with isolated macromolecules called unimers.

  9. Phospholipid - Wikipedia

    en.wikipedia.org/wiki/Phospholipid

    Phospholipids [1] are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group and two hydrophobic "tails" derived from fatty acids, joined by an alcohol residue (usually a glycerol molecule). Marine phospholipids typically have omega-3 fatty acids EPA and DHA integrated as part of the phospholipid molecule. [2]
