WebHydroxyl groups (-OH), found in alcohols, are polar and therefore hydrophilic (water liking) but their carbon chain portion is non-polar which make them hydrophobic. WebThe hydrophobic core impedes the difusion of hydrophilic structures, such as ions and polar molecules but allows hydrophobic molecules, which can dissolve in the membrane, cross it with ease. No, as the head is not hydrophobic, it is actually hydrophilic. Due to their electronic structure, water molecules may accept two hydrogen bonds and donate 2, thus being simultaneously engaged in a total of 4 hydrogen bonds.
