L-Carnitine: The Fatty-Acid Transport Cofactor in Research
Research compounds for laboratory use only · not medical advice
L-carnitine, the quaternary ammonium compound essential for mitochondrial fatty-acid transport, and its research in lipid metabolism and bioenergetics.
L-carnitine is not a peptide — it is a small molecule with a big job: it is the shuttle that moves long-chain fatty acids across the mitochondrial membrane so they can be oxidized. Every cell-culture experiment that touches fatty-acid metabolism eventually meets carnitine.
The molecule
L-carnitine (C₇H₁₅NO₃, ≈ 161 g/mol) is a quaternary ammonium compound. Its biological role is shuttling long-chain fatty acids into the mitochondrial matrix for β-oxidation via the carnitine shuttle — a mechanism that makes it foundational to lipid-metabolism and mitochondrial research.
What the research looks at
- Lipid metabolism — fatty-acid transport and oxidation pathways
- Mitochondrial bioenergetics — where carnitine’s shuttle role intersects ATP production
- Cell-culture supplementation — a common additive in metabolic assays
Its redox-adjacent partner in supplementation research is Glutathione.
