To make matters more vexing, none of these molecules can do their jobs without fatty lipids, which provide the membranes that cells need to hold their contents inside.
First, the size of a thiophene molecule is much larger than that of a hydrogen molecule so that there are some nickel particles in narrow places that thiophene molecules have difficulties contacting with while hydrogen molecules can do that easily.
Such a system has obvious advantages, given that while DNA is unable to sense distant changes in expression or copy-number, mRNA molecules can do so.
Although it does not answer the question I raised (its growth requires substrates prepared by humans), it suggests great possibilities of what RNA molecules can do (it was generated by (only) six rounds of in vitro selection).
Yet evidently humans, large assemblies of molecules, can compute, and it has been a thrilling challenge to develop smaller, simpler, synthetic assemblies of molecules that can do useful computation.
By understanding biological systems, by understanding what I told you before about what I call hub proteins or hub molecules, perhaps we can do what I call molecular prevention where we will be able to intervene early.
"Small changes in the molecule can make it either not effective or tremendously potent".
Although formally we need the Avogadro number NA to relate the measured affinity and the affinity of a single molecule (or single fragment), we can do without NA because the MW (Da) (molecular descriptor) and the mole of a substance MW (g/mol) (a property) are the same values.
For one thing, the changes you can make to proteins, turning small improvements into significant therapeutic advances, pales in comparison to what you can do to small molecule drugs.
