An example of the protein-protein interactions is the antigen-antibody interactions. Because of the complexity of the protein molecules, the hydrophobic interactions are more dominant.
Hydrophobic interactions are non covalent interactions between nonpolar molecules or regions within a molecule. They are based on the tendency of nonpolar molecules to minimize contact with water molecules.
Hydrogen bonds are not hydrophobic. In fact, hydrogen bonds are typically important in stabilizing the structure of many hydrophilic molecules in water by forming between polar molecules or within the same molecule. Hydrophobic interactions, on the other hand, are interactions between non-polar molecules that tend to be repelled by water.
Ionic bonds are not inherently hydrophobic; rather, they are generally polar in nature. However, the presence of ionic bonds does not necessarily make a compound hydrophobic or hydrophilic, as the overall polarity of the molecule and its interactions with water molecules will determine its solubility in water.
Nonpolar molecules are typically hydrophobic, meaning they do not mix well with water. This is because water is a polar molecule and tends to interact more strongly with other polar molecules. Hydrophobic molecules generally prefer to interact with each other instead of with water.
The lipid tails of a phospholipid molecule are hydrophobic, as they consist of nonpolar fatty acid chains that repel water.
Hydrophobic interactions are non covalent interactions between nonpolar molecules or regions within a molecule. They are based on the tendency of nonpolar molecules to minimize contact with water molecules.
The molecule is nonpolar and hydrophobic.
This is called the hydrophobic 'side' of the phospholipid molecule
Hydrophobic describes molecules that are repelled by water. You can determine if a molecule is hydrophobic by looking at its structure - if it contains mostly nonpolar covalent bonds or hydrophobic functional groups (e.g. alkyl groups), it is likely to be hydrophobic. Additionally, hydrophobic molecules tend to aggregate together in water due to the hydrophobic effect.

A hydrophobic molecule is more likely to be nonpolar.

Hydrophilic, or 'water loving' refers to molecules that are easily miscible in water. Polar molecules and ionic compounds are generally hydrophilic, and non-polar molecules are generally hydrophobic.See the Related Questions to the left for more information about how to determine if a molecule is non-polar, polar, or ionic.
The polarity of a molecule determines whether it is hydrophilic (attracted to water) or hydrophobic (repelled by water). If a molecule is polar, it is typically hydrophilic, meaning it can dissolve in water. If a molecule is nonpolar, it is usually hydrophobic and does not mix well with water.
Nonpolar molecules are typically hydrophobic, meaning they do not mix well with water. This is because water is a polar molecule and tends to interact more strongly with other polar molecules. Hydrophobic molecules generally prefer to interact with each other instead of with water.
A molecule that is both hydrophobic and polar has a nonpolar region that repels water (hydrophobic) and a polar region that interacts with water (polar). This unique combination of properties allows the molecule to dissolve in both water and nonpolar solvents.
It breaks the hydrogen bonds and hydrophobic interactions between different parts of the protein molecule. Proteins are composed of amino acid subunits linked together by peptide bonds—this is called a polypeptide and is also known as the primary structure of a protein. The primary structure interacts with itself (also known as folding) forming hydrogen bonds and hydrophobic interactions with different parts of the same molecule. Heat disrupts the hydrogen bonds and hydrophobic interactions leaving the protein to unfold when it is heated. Since heat is not strong enough to break the peptide bonds between the amino acid subunits, the primary structure remains intact. Once the protein is cooled again, the hydrogen bonds and hydrophobic interactions can reform since they are based on the makeup of the primary structure and it hasn't changed. :) Hope this helps.
