Document Summary

Majority on polymer interactions are not covalent. We have chemical diversity through monomers that form polymers. Order they are put together gives further diversity for polymer functionality. (cid:1) These structures are responsible for organizing cells, forming compartments, which are important. (cid:1) Ester is formed from condensation of ester alcohol. For proteins amides make up the back bone. We also mentioned how these covalent bonds are strong, yet reversible. They allow formation and breakage, and we can modify reaction conditions with chemicals and thermodynamics, depending on what we need to happen in the cell. (cid:1) (cid:1) (cid:1) (cid:1) Able to make changes to strucutres without changing the whole structure. Modularity allows expensive things to be maintained, and that modularity if provided in part by covalent bonds (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Association of 2 chains, the intermolecular reactions, is non-covalent. Dna can unzip and re-zip, under low energy costs.
