Metabolite Identification
Common NameDiethylphosphate
DescriptionDiethylphosphate belongs to the class of organic compounds known as dialkyl phosphates. These are organic compounds containing a phosphate group that is linked to exactly two alkyl chain. Diethylphosphate exists in all living organisms, ranging from bacteria to humans. Diethylphosphate has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make diethylphosphate a potential biomarker for the consumption of these foods. Diethylphosphate is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a small amount of articles have been published on Diethylphosphate.

Enzymes

General function:
Involved in arylesterase activity
Specific function:
Has low activity towards the organophosphate paraxon and aromatic carboxylic acid esters. Rapidly hydrolyzes lactones such as statin prodrugs (e.g. lovastatin). Hydrolyzes aromatic lactones and 5- or 6-member ring lactones with aliphatic substituents but not simple lactones or those with polar substituents.
Gene Name:
PON3
Uniprot ID:
Q15166
Molecular weight:
39607.185
Reactions
Paraoxon + Water → Diethylphosphate + 4-Nitrophenoldetails
General function:
Involved in arylesterase activity
Specific function:
Hydrolyzes the toxic metabolites of a variety of organophosphorus insecticides. Capable of hydrolyzing a broad spectrum of organophosphate substrates and lactones, and a number of aromatic carboxylic acid esters. Mediates an enzymatic protection of low density lipoproteins against oxidative modification and the consequent series of events leading to atheroma formation.

General function:
Involved in arylesterase activity
Specific function:
Capable of hydrolyzing lactones and a number of aromatic carboxylic acid esters. Has antioxidant activity. Is not associated with high density lipoprotein. Prevents LDL lipid peroxidation, reverses the oxidation of mildly oxidized LDL, and inhibits the ability of MM-LDL to induce monocyte chemotaxis.
