Equally important to mechanical properties are the new transport properties and membrane separation capabilities that structured, composite chemical products can deliver.
The chemical knowledge and new catalysis are embedded in the process, but other factors are necessary as well.
Perhaps the most important chemical reactions in the body involve adenosine triphosphate, or ATP. Below is my first attempt at looking at this.
Bohr discovered that an atom's electrons surround the dense positive nucleus but can move only in very specific regions called shells or orbits. Late-twentieth century advances in chemistry have considerably improved the quality of modern life.
Exothermic reactions increase heat energy in their environments; endothermic reactions absorb heat energy from their environment. The converse is true for endothermic reactions. The degree of movement determines the temperature of the molecule; the collective total of the movements determines the heat content of the system.
Even with optimum concentration and temperature, the probability of collisions between atoms in molecules may not produce products directly. In theory, any chemical reaction can proceed in either direction under the right conditions.
