Hydrophobic

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.

Lipid

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

Phospholipid Bilayer

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

Phospholipids

Science / Biology / Phospholipids: Asymmetrical lipid molecules with a hydrophilic head and a hydrophobic tail. Lipids with a phosphate group in place of one of the three fatty acid chains. Phospholipids are the building blocks of cell MORE
