Webcharacteristic linkage of lipophilic and hydrophilic groups in the molecular structure. The molecules are too big and complex in size and therefore are not ﬂexible enough to cover the interfaces being formed during homogenization of oil–water mixtures fast enough to create a long-term stable emulsion with sufﬁ-ciently small droplet diameter. WebA hydrophilic molecule (or region of a molecule) is one that is attracted to water. The phosphate heads are thus attracted to the water molecules of both the extracellular and intracellular environments. The lipid tails, on the other hand, are uncharged, or nonpolar, and are hydrophobic—or “water fearing.”
