Structure of membranes where heads face outside and tails are on inside
Short molecule made up of hydrocarbon chains that packs closely with the tails. Can flip leaflets very easily.
Helps lipids in bilayer flip-flop their position
Fatty acid attached to sphingosine (base derived from serine) with a head group of sugars.
GPI. Is a glycolipid that can be attached to the C-terminus of a protein during posttranslational modification and is used as a GPI anchor in biological processes. Oligosaccharide attached to -OH of inositol C2.
Backbone of lipids. CH2 groups with OH groups.
Integral membrane protein
Have segment(s) that crosses the membrane and that segment is hydrophobic so that it can sit in the nonpolar center of the membrane. Hydropathy plots will show which sement this is and can help id if a protein is an IMP.
Made of sphigolipids that pack very tightly together
Peripheral membrane protein
Associated with the cytoplasmic or luminal surface of the cell membrane. Can be through covalent binding with lipd tails., electrostatic interactions with the polar lipid heads, partial insertion of a hydrophobic region, association with a cytoplasmic protein
A phospholipid with choline esterified to the phosphate, neutral
A phospholipid with inositol esterified to the phosphate, charge: -1
A phospholipid with serine esterified to the phosphate, charge: -1
A phospholipid with glycerol esterified to the phosphate, charge: -1
A sphingolipid with choline or serine as a head group
Region of a IMP that crosses the lipid membrane
