Research brief · Metabolic
L-Carnitine
Mitochondrial fatty-acid shuttle used in β-oxidation and bioenergetics research.
Class
Quaternary amine / amino-acid derivative
Half-life
~15 h (systemic)
Studied in
Fatty-acid β-oxidation, mitochondrial bioenergetics and adipose-research models.
What it is
L-Carnitine is an endogenous quaternary amine required for the transport of long-chain fatty acids into the mitochondrial matrix. In research it is used as a substrate / cofactor probe in β-oxidation, mitochondrial bioenergetics and adipose-tissue studies.
Mechanism studied
Mitochondrial long-chain fatty-acid shuttle via carnitine palmitoyltransferase (CPT-1/2).
Research notes
- Often paired with Lipo-C and B12 in injectable lipotropic research blends.
- Reference cofactor for CPT-1/CPT-2 enzyme assays.
Before sourcing any material
- Confirm a lot-matched third-party certificate of analysis (HPLC purity and mass-spectrometry identity).
- Check the stated peptide content per vial, not just the gross vial mass.
- Plan reconstitution volumes first so the vial size matches your protocol.
- Verify what is lawful in your jurisdiction — these are in-vitro research reagents, not medicines.
