WebToxicokinetics is the mathematical description of the uptake and disposition of a chemical in the body. Toxicokinetic modeling is usually implemented by describing the time course of the amount or concentration of the parent substance and its metabolites in one or several body compartments. Four potential processes exist for a chemical interacting with an animal: absorption, distribution, metabolism and excretion (ADME). Absorption describes the entrance of the chemical into the body, and can occur through the air, water, food, or soil. Once a chemical is inside a body, it can be distributed to other areas of the body through diffusion or other biological processes. At this point, the chemical may undergo metabolism and be biotransformed into other chemicals (meta… death in the woods sherwood anderson

"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. " - Toxicokinetics and metabolism
