Title: bioresorption
Long Title: IUPAC Gold Book - bioresorption
DOI: 10.1351/goldbook.13928
Status: current

Definition
Disappearance of a substance from an organism by processes of metabolism, secretion, or excretion.

Notes
1) Bioresorption is now considered as pertinent and should be used specifically only when foreign material and residues have been shown assimilated or eliminated from the living host, regardless of the followed route, namely, lungs or kidneys or insertion in biochemical processes.
2) In the case of polymers or high-molar-mass macromolecules that are retained in parenteral compartments, degradation or biodegradation is necessary prior to bioresorption.
3) This concept does not apply to the environment as everything, including degradation by-products issued from outdoor degradation or biodegradation can only be stored or chemically transformed on Earth, so far.
