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

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

    Ethanol's hydrophobic properties are limited and primarily binds close the hydrophilic region of the phospholipid. This bonds creates strong hydrogen bonds and leads to a strong interlocking amongst the acyl chains 5) why the presence of cholesterol; a sterol compound, inhibits ethanol's ability to disrupt the membrane and 6) deriving the ...

  4. Pulmonary surfactant - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_surfactant

    The proteins and lipids that make up the surfactant have both hydrophilic and hydrophobic regions. By adsorbing to the air-water interface of alveoli, with hydrophilic head groups in the water and the hydrophobic tails facing towards the air, the main lipid component of surfactant, dipalmitoylphosphatidylcholine (DPPC), reduces surface tension.

  5. Heat shock response - Wikipedia

    en.wikipedia.org/wiki/Heat_shock_response

    Exposed hydrophobic residues are a major problem with regards to protein aggregation because they can interact with one another and form hydrophobic interactions. [20] It is the job of chaperones to prevent this aggregation by binding to the residues or providing proteins a "safe" environment to fold properly. [ 21 ]

  6. Lipid bilayer - Wikipedia

    en.wikipedia.org/wiki/Lipid_bilayer

    The first region on either side of the bilayer is the hydrophilic headgroup. This portion of the membrane is completely hydrated and is typically around 0.8-0.9 nm thick. In phospholipid bilayers the phosphate group is located within this hydrated region, approximately 0.5 nm outside the hydrophobic core. [9]

  7. 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

  8. Amphiphile - Wikipedia

    en.wikipedia.org/wiki/Amphiphile

    The phospholipid amphiphiles are the major structural component of cell membranes. Amphiphiles are the basis for a number of areas of research in chemistry and biochemistry, notably that of lipid polymorphism. Organic compounds containing hydrophilic groups at both ends of the molecule are called bolaamphiphilic.

  9. Membrane lipid - Wikipedia

    en.wikipedia.org/wiki/Membrane_lipid

    Phospholipids and glycolipids consist of two long, nonpolar (hydrophobic) hydrocarbon chains linked to a hydrophilic head group. The heads of phospholipids are phosphorylated and they consist of either: Glycerol (and hence the name phosphoglycerides given to this group of lipids), or; Sphingosine (e.g. sphingomyelin and ceramide).
