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.

Lipids

Science / Biology / Lipids: One of the four classes of organic macromolecules. Lipids function in the long-term storage of biochemical energy, insulation, structure and control. Examples of lipids include the fats, waxes, oils a MORE

Phospholipid

Science / Chemistry / Phospholipid: An ester of glycerol with two fatty acids and phosphoric acid (H3PO4) or a derivative of phosphoric acid group (like H2PO4CH2CH2N(CH3)3). Phospholipids have a hydrophilic head (the phosphate group) an MORE

Glycolipids

Science / Biology / Glycolipids: Polysaccharides formed of sugars linked to lipids, a part of the cell membrane. 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

Fat

Health / Fitness / Fat: Often referred to as lipids, or triglycerides, one of the main food groups, containing nine calories per gram. It serves a variety of functions in the body, however a high percentage of body fat has b MORE
