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) and a lipophilic tail (the fatty acids).

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

Endoplasmic Reticulum (ER)

Science / Biology / Endoplasmic Reticulum (ER): A network of membranous tubules in the cytoplasm of a cell; involved in the production of phospholipids, proteins, and other functions. Rough ER is studded with ribosomes; smooth ER is not. MORE
