Questions to answer in the process
Looking at what we saw and adding some new stuff
Lipid rafts (~ 50nm)
Sphingolipids (long saturated chains)
GEF, AKT, migrating front
Lipid molecules: phospholipids, cholesterol, glycolipid, all amphipathic
Lipid bilayer, hydrophobic inside and hydrophilic outside
Subdomains on membrane, asymmetry important for functions
Phospholipids as signals
Integral membrane protein
Peripheral membrane protein
Glycosylphosphatidylinositol (GPI) anchor protein
Fatty acid chain (acyl, N-terminal) or prenyl group modifications (C-terminal)
Sugar are added in the lumen of the ER and Golgi apparatus, therefore, sugar are outside of cell surface
Cytosol has reduced environment, preventing disulfide bonds
Tight Junction is one kind of them
Proteins and lipids on the outer layers can’t move to other compartments
Looking at how the cell work live!!!!
