How to Make Bread A Quick Overview of the Process, The Role of Butter, Eggs, Milk and Sugar in Enriched Bread (+ Brioche Recipe). It is dipole induced so that it is dipole interactions. While water includes dipole-dipole interactions, it also contains hydrogen bonding. Hydrophilic substances are essentially polar molecules (or a portion of molecule). WebGiven the fact that selective leaching of hydrophilizing polymeric additives is the ultimate change in the membrane, the membrane is expected to turn more hydrophobic. These interactions can be further classified into polar interactions with hydrogen bond donors (e.g., backbone NH, polarized CH, polar side chains, and protein bound water), hydrophobic interactions with lipophilic side chains, and orthogonal multipolar interactions, with backbone carbonyl groups, amide containing side chains (Asn and Gln), Solubility depends on polarity but that doesn't mean that all polar substances will dissolve in water or any other polar solvent.
