58 QUESTIONS AND ANSWERS
2024/2025 RATED A+
cholesterol
won't spontaneously help turn into lipid bilayer,just fits into bilayer
vesicle
lipid bilayer
hollow spheres that have aqua interiors and stabilized by hydrophobic effect
plasma membrane
outer leaflet: sphingolipids, PC, glycolipids
inner leaflet:PE, PS, PI
membrane proteins
integral proteins
peripheral proteins
peripheral
membrane proteins
bind to surface through polar interactions, reversible binding associated with outer
environ
can have lipid anchor covalently bound to protein helps protein attach to membrane
, integral
membrane proteins
embeded in lipid bilayer
Nonpolar section of membrane
often alpha helix ~20 amino acid
Defined orientation
E.g N-Terminus outside
N-Terminus
is the start of a protein or polypeptide referring to the free amine group (-NH2) located at
the end of a polypeptide
hydropathy index
-how nonpolar amino acid seq is
-also some membrane proteins with beta barrel
-also charged resides on membrane surface portions, aromatic residues
Beta barrel membrane proteins
found in the outer membranes of bacteria, mitochondria and chloroplasts.
fatty acids
Isoprene derivative
GPI-glycosyl phosphatidyl inostitol
