  2. Glycerophospholipid - Wikipedia

    en.wikipedia.org/wiki/Glycerophospholipid

    Each glycerophospholipid molecule consists of a small polar head group and two long hydrophobic chains. In the cell membrane, the two layers of phospholipids are arranged as follows: the hydrophobic tails point to each other and form a fatty, hydrophobic center; the ionic head groups are placed at the inner and outer surfaces of the cell membrane

  3. Membrane lipid - Wikipedia

    en.wikipedia.org/wiki/Membrane_lipid

    Membrane lipids are a group of compounds (structurally similar to fats and oils) which form the lipid bilayer of the cell membrane. 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 ...

  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. 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]

  6. Plasmalogen - Wikipedia

    en.wikipedia.org/wiki/Plasmalogen

    Plasmalogens are a class of glycerophospholipid with a plasmenyl group linked to a lipid at the sn-2 position of the glycerol backbone. Plasmalogens are found in multiple domains of life, including mammals , invertebrates , protozoa , and anaerobic bacteria.

  7. Category:Lipids - Wikipedia

    en.wikipedia.org/wiki/Category:Lipids

    Lipids are a class of relatively water-insoluble organic molecules, which are the "basic" components of biological membranes. There are three forms of lipids: phospholipids , steroids , and triglycerides .

  9. Glycolipid - Wikipedia

    en.wikipedia.org/wiki/Glycolipid

    Fatty acids are connected to this backbone, so that the lipid as a whole has a polar head and a non-polar tail. The lipid bilayer of the cell membrane consists of two layers of lipids, with the inner and outer surfaces of the membrane made up of the polar head groups, and the inner part of the membrane made up of the non-polar fatty acid tails.
