  2. 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]

  3. Lipid bilayer - Wikipedia

    en.wikipedia.org/wiki/Lipid_bilayer

    The three main structures phospholipids form in solution; the liposome (a closed bilayer), the micelle and the bilayer. [1] The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around all cells.

  4. Lipid - Wikipedia

    en.wikipedia.org/wiki/Lipid

    Lipids are a broad group of organic compounds which include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others. The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes.

  5. Membrane lipid - Wikipedia

    en.wikipedia.org/wiki/Membrane_lipid

    The three major classes of membrane lipids are phospholipids, glycolipids, and cholesterol. 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 ...

  6. Lipoprotein - Wikipedia

    en.wikipedia.org/wiki/Lipoprotein

    ApoA, ApoB, ApoC, ApoE are apolipoproteins; green particles are phospholipids; T is triglyceride; C is cholesterol ester. A lipoprotein is a biochemical assembly whose primary function is to transport hydrophobic lipid (also known as fat) molecules in water, as in blood plasma or other extracellular fluids.

  7. Biological membrane - Wikipedia

    en.wikipedia.org/wiki/Biological_membrane

    Cross-sectional view of the structures that can be formed by phospholipids in an aqueous solution. A biological membrane, biomembrane or cell membrane is a selectively permeable membrane that separates the interior of a cell from the external environment or creates intracellular compartments by serving as a boundary between one part of the cell and another.

  8. Glycerophospholipid - Wikipedia

    en.wikipedia.org/wiki/Glycerophospholipid

    Cells will use this phosphatidylserine to enter cells via apoptotic mimicry. The structure of this lipid differs in plants and animals, regarding fatty acid composition. In addition, phosphatidylserine plays an important role in the human brain content, as it makes up 13–15% of the phospholipids in the human cerebral cortex.

  9. Cell membrane - Wikipedia

    en.wikipedia.org/wiki/Cell_membrane

    Illustration of a eukaryotic cell membrane Comparison of a eukaryotic vs. a prokaryotic cell membrane. The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of a cell from the outside environment (the extracellular space).
