1 The molecules are absorbed into the bloodstream and consequently affect the organs.
2 In this new shape, it can accommodate molecules called G-proteins, which hang around inside the cell.
3 Organic compounds contain carbon in their molecules.
4 The molecules of oxygen gas contain just two atoms.
5 Professor Orr has developed interesting ways of tagging chemical molecules using existing laboratory lasers.
6 Professor Bonnet has been working for many years on molecules of this type.
7 The structure of molecules can be seen under an electron microscope.
8 The protein molecule is made up of a number of organic units known as amino acids.
9 In cases where no data were available, the most probable structure of a molecule was calculated using molecular mechanics.
10 The chemical structure of this particular molecule is very unusual.
11 As students of chemistry know, even small rearrangements of a molecule's structure can produce a compound that acts differently.
