That in turn gives rise to proteins, the molecules that do the work inside a cell.
But it can't efficiently capture proteins — the molecules that do the real work inside cells.
"Once you know the molecules that do the work, scientists can design different compounds to deal with the problem".
The MgO and TiO2 surfaces clearly appear to be predominantly acidic and molecules that do not dissociate generally bind to the metal cation.
Molecules that do just that have been created in the lab, or, more precisely, have been allowed to create themselves by a process of chemical natural selection.
The proteins, in turn, become the blocks of tissues and the enzymes, hormones and carrier molecules that do most of the cell's work.
An alternative strategy for producing porous materials is to design less symmetrical molecules that do not crystallize and pack inefficiently in the solid state.
When a pharmaceutical company develops a drug, the challenge isn't only to find molecules that do the right things in a test tube.
In the first case, the protein cannot fold, while in the second, the small fraction of molecules that do fold adopt the correct structure.
To aid in the design of drug molecules that do not bind to HSA, the structures of HSA/ligand complexes would be very useful.
Antibodies, even when expressed in smaller engineered formats, are large molecules that do not enter the brain in sufficient amounts for imaging purposes.
