Emulsifiers can be used to mix oil and water and in this case they do that by sitting both in the water and oil phase with a different part of the molecule. For example, according to some schemes, it is found in the interior due to its high reactivity (Fiser et al., 1996), while others consider it polar (REF). Note that the term hydrophilic does not necessarily refer to an entire molecule, and that interacting strongly with a molecule or a part of a molecule does not imply that it must be soluble in water. , , When considering polarity, some amino acids are straightforward to define as polar, while in other cases, we may encounter disagreements. If the surface has an affinity for liquid, it is considered to have high surface wettability (hydrophilic). This question isn't about biology but about learning it, so no doubt it will be closed very soon. The most common example of hydrophobic molecules in foods are fats and oils.

Weba. c. the element is required in very small amounts. As Davin suggested, it remains HO, but the distance between the molecules increases and makes the intermolecular attraction weaker. These residues typically form the hydrophobic core of proteins, which is isolated from the polar solvent. For instance, if there is an atom that pulls strongly on both the left and right side of a molecule, with the rest being even, those two forces will probably cancel each other out. I know this isn't how you are "supposed" to do it, but it isn't easy to memorize all 20 amino acids, and this helps a lot with identifying whether they are hydrophobic or hydrophilic.
