Document Summary
Vocabulary for vocabulary quiz 2 (refer to glossaries of chapter 2, 3, and 5) Fluid mosaic model - describes the structure of the plasma membrane as a mosaic of components including phospholipids, cholesterol, proteins, glycoproteins, and glycolipids (sugar chains attached to proteins or lipids, respectively), resulting in a fluid character (fluidity). Lipid - macromolecule that is nonpolar and insoluble in water. Hydrocarbon - molecule that consists only of carbon and hydrogen. Phospholipid - major constituent of the membranes; composed of two fatty acids and a phosphate containing group attached to a glycerol backbone. Triglyceride - fat molecule; consists of three fatty acids linked to a glycerol molecule. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. Fatty acid - a carboxylic acid consisting of a hydrocarbon chain and a terminal carboxyl group, especially any of those occurring as esters in fats and oils.
