Terms in this set (38)

plasma membrane
A selectively-permeable phospholipid bilayer forming the boundary of the cells
fluid mosaic model
The representation of the plasma membrane as a dynamic phospholipid bilayer with interactions of cholesterol, proteins, and carbohydrates
glycoprotein coat
carbohydrates associated with membrane-bound proteins
phospholipid
a lipid containing a phosphate and alcohol joined to hydrophobic fatty acid tails
lipid rafts
collections of similar lipids with or without associated proteins that serve as attachment points for other biomolecules
flippase
enzyme embedded in plasma membrane; functions to move lipids from one face to the other
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
triacylglycerol
storage lipid involved in human metabolic processes
unsaturated fatty acid
A fatty acid possessing one or more double bonds between the carbons in the hydrocarbon tail
chylomicrons
the class of lipoproteins that transport lipids from the intestinal cells to the rest of the body
glycerophospholipid
a lipid containing a glycerol backbone with a phosphate group; bound by ester linkages to two fatty acids
liposome
small membrane bounded transport vesicle
sphingolipid
a lipid containing a sphingosine or sphingoid backbone bound to fatty acid tails; includes ceramide, sphingomyelins, glycosphingolipids, and gangliosides
cholesterol
A lipid that forms an essential component of animal cell membranes and acts as a precursor molecule for the synthesis of other biologically important steroids
transmembrane protein
an integral membrane protein that passes completely through the phospholipid bilayer
