Buy L-Carnitine 600mg – High-Purity Research Compound
When you Buy L-Carnitine 600mg from Sino Research Peptide Manufacturer, you get a natural quaternary ammonium compound built for demanding lab work. Chemically known as β-hydroxy-γ-N-trimethylaminobutyric acid, L-Carnitine forms naturally in the liver and kidneys from lysine and methionine. In the inner mitochondrial membrane, it plays an essential role in fatty acid β-oxidation, transporting long-chain acyl-CoA esters through the carnitine shuttle system (CPT I and CPT II).
Researchers Buy L-Carnitine 600mg to study energy metabolism, lipid utilization, mitochondrial function, oxidative stress, muscle bioenergetics, and age-related metabolic decline. We supply it as high-purity L-Carnitine base or L-Carnitine L-tartrate powder, verified through HPLC, in 600mg vials and bulk quantities. Every batch is produced in CHINA, and it’s one of the main reasons labs choose to Buy L-Carnitine 600mg from our catalog instead of an unverified source.
Important: L-Carnitine 600mg is for sale strictly for research use. It is not for human consumption.

Molecular and Physical Data
| Property | Value |
|---|---|
| Molecular Formula | C₇H₁₅NO₃ (free base) |
| Molecular Weight | 161.20 Da |
| CAS Number | 541-15-1 (L-Carnitine free base) |
| Appearance | White crystalline powder |

| Stereochemistry | Naturally produced L-enantiomer |
L-Carnitine is a zwitterionic compound. It carries a positively charged trimethylammonium moiety alongside a negatively charged carboxylate. Notably, the D-isomer is pharmaceutically inactive, so only the L-enantiomer supports biological activity. This quaternary ammonium structure allows L-Carnitine to bind carnitine-acylcarnitine translocase, which drives mitochondrial β-oxidation and ATP synthesis.
Mechanism of Action
L-Carnitine transports long-chain fatty acids into mitochondria through CPT1/2 and the carnitine-acylcarnitine translocase. This process generates acetyl-CoA for the TCA cycle and subsequent ATP production. Beyond transport, L-Carnitine performs several additional roles:
Metabolic Buffering
L-Carnitine buffers acetyl-CoA buildup during high-fat metabolism and mitigates toxic acyl-CoA accumulation in metabolic disease models.
Antioxidant Activity
L-Carnitine scavenges free radicals and chelates metal ions, giving it a meaningful antioxidant role in oxidative stress research.
Membrane Stabilization
L-Carnitine regulates membrane fluidity and stabilizes mitochondrial membranes, which supports its use in mitochondrial dysfunction studies.
Enzyme Modulation
L-Carnitine modulates fatty acid oxidation enzymes through PPAR pathways. Researchers note that carnitine deficiency links to mitochondrial dysfunction, muscle weakness, and lipid accumulation.
Research Applications
Labs buy L-Carnitine 600mg for a wide range of experimental purposes, including:
| Research Application | Focus Area |
|---|---|
| Mitochondrial fatty acid transport | β-oxidation efficiency |
| Energy metabolism studies | Muscle, liver, and heart tissue |
| Metabolic disorder modeling | Exercise physiology, age-related decline |
| Oxidative stress research | Antioxidant and anti-inflammatory activity |
| Neuroprotection studies | Neuronal cultures, ischemia models |
| Lipid metabolism experiments | Control or co-treatment compound |
Thanks to its 600mg size, this compound works well across cell culture, isolated mitochondria, organ perfusates, and small-animal metabolic studies.
Preclinical Research Summary
Key Findings by Model Type
| Model Type | Dosage Range Studied | Key Finding |
|---|---|---|
| Skeletal muscle / cardiac (rat) | 0.5–2 g/kg diet or 100–500 mg/kg i.p. | Increased fatty acid oxidation, reduced lactate, improved endurance |
| Ischemia-reperfusion injury | 200–400 mg/kg i.v. | Reduced infarct size, preserved ATP, less oxidative damage |
| Aging research | Varies by model | Restored mitochondrial function, reduced lipid peroxidation |
| Neuroprotection (Parkinson’s, Alzheimer’s) | Varies by model | Protected dopaminergic neurons against amyloid-β toxicity |
| In vitro hepatocytes / myocytes | 1–10 mM | Protected against lipid overload and oxidative stress |
