Science / Chemistry / Hydrophobic: A nonpolar molecule or group that has little affinity for water. Hydrophobic groups on molecules in solution tend to turn in on themselves or clump together with other hydrophobic groups because they are unable to disrupt the network of strong hydrogen bonds in the water around them.
Science / Chemistry / Lipid: A diverse group of organic molecules that contain long hydrocarbon chains or rings and are hydrophobic. Examples are fats, oils, waxes, and steroids. MORE
Science / Chemistry / Phospholipid Bilayer: In an aqueous environment phospholipids can form a two-layered 'sandwich' with the hydrophobic lipid tails on the inside and the hydrophilic phosphate heads facing outward. These bilayers are the esse MORE
