  2. Hydrophobicity scales - Wikipedia

    en.wikipedia.org/wiki/Hydrophobicity_scales

    The hydrophobic effect represents the tendency of water to exclude non-polar molecules. The effect originates from the disruption of highly dynamic hydrogen bonds between molecules of liquid water. Polar chemical groups, such as OH group in methanol do not cause the hydrophobic effect.

  3. Non-covalent interaction - Wikipedia

    en.wikipedia.org/wiki/Non-covalent_interaction

    The hydrophobic effect is the desire for non-polar molecules to aggregate in aqueous solutions in order to separate from water. [22] This phenomenon leads to minimum exposed surface area of non-polar molecules to the polar water molecules (typically spherical droplets), and is commonly used in biochemistry to study protein folding and other ...

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

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

    The hydrophilic region contains the polar head group. This region is exposed to aqueous substances located mainly in the exterior portion of the biomembrane. The hydrophobic region consists of the non-polar acyl chains or fatty acids groups facing the interior of the biomembrane. Phospholipids consist of two non-polar hydrocarbon chains with ...

  5. Protein folding - Wikipedia

    en.wikipedia.org/wiki/Protein_folding

    The hydrophobic effect is the phenomenon in which the hydrophobic chains of a protein collapse into the core of the protein (away from the hydrophilic environment). [12] In an aqueous environment, the water molecules tend to aggregate around the hydrophobic regions or side chains of the protein, creating water shells of ordered water molecules ...

  6. Hydrophobic-polar protein folding model - Wikipedia

    en.wikipedia.org/wiki/Hydrophobic-polar_protein...

    The hydrophobic-polar protein folding model is a highly simplified model for examining protein folds in space. First proposed by Ken Dill in 1985, it is the most known type of lattice protein: it stems from the observation that hydrophobic interactions between amino acid residues are the driving force for proteins folding into their native state. [1]

  7. Hydrophobe - Wikipedia

    en.wikipedia.org/wiki/Hydrophobe

    The hydrophobic interaction is mostly an entropic effect originating from the disruption of the highly dynamic hydrogen bonds between molecules of liquid water by the nonpolar solute, causing the water to form a clathrate-like structure around the non-polar molecules.

  8. Thermodynamics of micellization - Wikipedia

    en.wikipedia.org/wiki/Thermodynamics_of_micelliz...

    Surfactants are composed of a polar head group that is hydrophilic and a nonpolar tail group that is hydrophobic. The head groups can be anionic, cationic, zwitterionic, or nonionic. The tail group can be a hydrocarbon, fluorocarbon, or a siloxane. Extensive variation in the surfactant’s solution and interfacial properties is allowed through ...

  9. Hydrophobic collapse - Wikipedia

    en.wikipedia.org/wiki/Hydrophobic_collapse

    Hydrophobic collapse is a proposed process for the production of the 3-D conformation adopted by polypeptides and other molecules in polar solvents. The theory states that the nascent polypeptide forms initial secondary structure (ɑ-helices and β-strands) creating localized regions of predominantly hydrophobic residues.
