WebToxicokinetics is essentially the study of "how a substance gets into the body and what happens to it in the body." Before this term was used, the study of the kinetics (movement) of chemicals was originally conducted with pharmaceuticals and the term pharmacokinetics became commonly used.

WebThe movement of molecules is called “kinetics” or “pharmacokinetics” and chemical properties such as polarity, molecule weight, molecular size, chirality, HOMO/LUMO, and many more all have an impact on the ADME potential of a molecule/toxin. ADME is generally used to describe the impact or a drug or pharmaceutical compound.
