Urinary Adipic Acid (Adipate)
Six-carbon saturated dicarboxylic acid generated via endoplasmic reticulum omega-oxidation of unburned hexanoic and palmitic fatty acids.
Standard vs. Optimal Reference Rangesug/mg Cr
Standard reference intervals represent the statistical 95% distribution of unselected commercial populations. Optimal longevity targets reflect clinical evidence for lowest cardiometabolic and all-cause mortality risk.
Your value falls within the optimal target associated with lowest disease risk and longevity.
<3.0 ug/mg Cr
General reference distribution across unselected commercial populations.
<1.5 ug/mg Cr
Concentration target associated with minimal all-cause cardiometabolic mortality.
Molecular Mechanism & Clinical Purpose
When mitochondrial beta-oxidation is impaired or carnitine is deficient, excess fatty acids undergo CYP4A omega-oxidation yielding adipic acid.
Differential Diagnosis
Elevated Levels (Adipate High)
- •Mitochondrial beta-oxidation defects
- •Functional carnitine deficiency (impaired CPT-1 shuttle)
- •High dietary intake of adipate-containing additives
Low Levels (Adipate Low)
- •Optimal mitochondrial fatty acid transport and beta-oxidation

Pre-Analytical Caveats & Diagnostic Workup
Pre-Analytical Considerations:
Specimen collection should follow standardized phlebotomy protocols. Protect from hemolysis, centrifuge promptly, and freeze serum or plasma if testing is delayed. Patient should be in a resting, fasting state where indicated.
Reflexive Testing Protocol:
- Confirmatory testing and secondary biomarker quantification for Adipate
- Targeted organ system imaging or functional dynamic testing related to peroxisomal omega-oxidation
- Comprehensive baseline metabolic, renal, and inflammatory assessment (CMP, CBC, hs-CRP)
