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