Document Summary
G = (cid:894)- h lipids + h water) + (-t (- s lipids + s water(cid:895) Lipid bilayer formation is driven by the hydrophobic effect to increase the motional freedom of water (+ s) to achieve stability of the system. H phospholipids are strongly bonded (strong bonds/ many bonds) + h phospholipids are weakly bonded (weak bonds/ few bonds) C h n o s p membrane, store energy, signaling. Special aa: glycine (symmetric), cysteine (disulfide bond is covalent), proline (links back to itself) Both protein and phospholipids are driven by the hydrophobic effect. Denaturation: due to disruption of non-covalent interactions, the protein will unfold/denature. Caused by temp. change, ph change, detergents, mutation/aa substitution, change in aqueous environment. Protein structure and assembly stability of bonds. Strength of new bond 2. size of new aa 3.
