Glycolipids

Family of lipids found exclusively in the noncytosolic leaflet of a bilayer

Saturated

Describes a hydrocarbon lipid tail lacking double bonds

Phospholipid

The most abundant membrane lipid

Cholesterol

Not found in bacterial membranes

Beta sheet

One of the protein folds found in multipass transmembrane proteins (2 Words)

Leaflet

Another word for 'the monolayer' of a lipid bilayer

Hydropathy plots

Used to predict stretches of hydrophobic amino acids that cross a lipid bilayer as an alpha helix (2 Words)

Tight Junctions

Maintains the asymmetric distribution of membrane proteins to apical/basal lateral subdomains in epithelial cells (2 Words)

Lipid Droplet

Surrounded by a single phospholipid monolayer; contains lipid molecules composed of only hydrophobic molecules (2 Words)

Transmembrane domain

Found in proteins that cross a lipid bilayer; formed by a stretch of hydrophobic amino acids (2 Words)

Lipid Rafts

Specialized lipid membrane subdomains found in animal cells (2 Words)

Lipid Anchor

Used to link soluble proteins to a membrane; often a reversible modification (2 Words)

Peripheral Membrane Proteins

Proteins that indirectly associate with a lipid bilayer through their association with a membrane protein (3 Words)

FRAP (Fluorescence Recovery After Photobleaching)

Method used to measure the lateral movement of membrane proteins within a membrane

Amphipathic

Property that describes lipid molecules; containing both hydrophobic and hydrophilic regions

Cortex

Underlies the plasma membrane; formed by cytoskeletal filaments; functions to restrict plasma membrane protein movement

Unsaturated

Describes a hydrocarbon lipid tail containing double bonds

Carbohydrates

Eukaryotes have a cell coat made of these

Alpha Helix

A second protein fold found in multipass transmembrane proteins (2 Words)

Phosphotidylserine

Moves to the extracellular monolayer leaflet signaling cell death

Flip-Flop

Movement of phopholipids between monolayers (2 Words)

Fluidity

Influenced by hydrocarbon chain length, number of unsaturated bonds, and temperature
