Biochemistry is the study of the physical and chemical mechanisms underlying biological systems.

Prefixed substituents are ordered alphabetically (excluding any modifiers corresponding to di-, tri-, etc.), e.g. chlorofluoromethane, not fluorochloromethane. If there are multiple useful groups of the identical type, both prefixed or suffixed, the place numbers are ordered numerically (thus ethane-1,2-diol, not ethane-2,1-diol.) The N place indicator for amines and amides comes before “1”, e.g. CH3CH(CH3)CH2NH(CH3) is N,2-dimethylpropanamine.
