Enantiomers are important to crystallography because many crystals are arrangements of alternate right- and left-handed forms of a single molecule. A complete description of the crystal specifies how the forms are mixed with each other. An example of a pair of substances that are enantiomers is ...
A "ligand" is the combination of a molecule and a substance, and a "conformational change" is a change in the shape of a molecule, so "ligand-induced conformational changes" are changes to the shape of a molecule caused by the molecule binding to other substances.And this is degree-level...
'Nitrogen-fixing bacteria' and 'ammonia-oxidizing bacteria' make the nitrogen molecule (N2) into 'ammonium ion (NH4+)' and 'nitrifying bacteria' turn the ammonium ion into nitrate (NO3-) again. Ammonium ions and nitrates are dissolved in water and absorbed into the roots of plants and then...
at the stereogenic centre, two isomers present in the molecule differ, while the rest remains identical. a molecule may contain numerous stereocenters leading to several stereoisomers. stereoisomers are isomeric molecules that possess the same constitution and molecular formula, but they vary in three...
The molar mass is the mass of one mole of a sample. To find the molar mass, add the atomic masses (atomic weights) of all of the atoms in the molecule. Find the atomic mass for each element by using the mass given in the Periodic Table or table of atomic weights. Multiply the subs...
The asymmetric unit contains a single dinuclear unit in which only one rhodium atom is bound by an axial pyridine molecule. The Rh Rh bond is 2.534(1) and the Rh N bond, 2.133(10) . Surprisingly, pairs of dinuclear units are linked together in the solid state via two long, 3.106 , ...

If a molecule has more than one type of atom, the most metallic or least electronegative atom goes in the center. If you don't knowthe electronegativity, remember the trend is that electronegativity decreases as you move away from fluorine on the periodic table. ...
