Document Summary

Proteins can be integral and peripheral act as functional entities. Do not freely diffuse: hydrophilic substances (ions and most natural solutes) Generate ion gradient by etc used for synthesis reactions, transport, motility. Protein/macromolecule export for components of external structures. Bacteria sense the environment for desired or noxious components. Bilayer (hydrophilic/charged/polar region on exterior, f. a. on the inside) What function do proteins serve in the om. What are the complexes involved in om assembly (lps and porin?: divalent cations: vital for structure. Only in the outer leaflet of the outer membrane in only gram-negative organisms.
