L-Carnitine 200mg Research Peptide: An Essential Metabolite for Fatty Acid Oxidation & Energy Metabolism Studies

If your research investigates mitochondrial function, lipid metabolism, or the molecular mechanisms of energy homeostasis, L-Carnitine 200mg research peptide offers a precisely defined and extensively validated synthetic tool. L-Carnitine is a naturally occurring quaternary ammonium compound synthesised from the amino acids lysine and methionine that plays an indispensable role in cellular energy production. It is an essential metabolite that facilitates the import of long-chain fatty acids into the mitochondria for β-oxidation. L-Carnitine is considered “conditionally essential,” with supplementation becoming relevant in specific research contexts. This makes L-Carnitine 200mg research peptide a valuable tool for laboratories investigating mitochondrial biology, metabolic regulation, cardiovascular health, and neurodegenerative disorders.

At Chinese Grey Peptides, we supply high‑purity L-Carnitine 200mg research peptide to research institutions and wholesale buyers across the United Kingdom, France, Germany, Spain, Sweden, Italy, and the USA. Every batch is lyophilised, HPLC‑verified to ≥98% purity, and accompanied by a Certificate of Analysis (COA), ensuring your investigations into mitochondrial function, lipid metabolism, and cellular energy regulation begin with uncompromising quality.

What Is L-Carnitine and How Does It Work?

To fully appreciate the research potential of L-Carnitine 200mg research peptide, it is essential to understand its biochemical structure, its role as a critical metabolic regulator, and the mechanisms by which it exerts its effects.

The Naturally Occurring Quaternary Ammonium Compound

L-Carnitine is a nutrient-like compound synthesised from the amino acids lysine and methionine, with the support of vitamin C. Its molecular formula is C₇H₁₅NO₃, and its molecular weight is 161.20 g/mol. The compound is available in several supplement forms, including L-carnitine (the basic form), Acetyl-L-carnitine (ALCAR), Propionyl-L-carnitine, and L-carnitine L-tartrate (LCLT), each with distinct research applications.

Mechanism of Action: Mitochondrial Fatty Acid Transport & Energy Production

The biological activity of L-Carnitine 200mg research peptide is mediated through its central role in mitochondrial metabolism:

• Facilitation of Long-Chain Fatty Acid Transport: L-carnitine acts as a shuttle, transporting long-chain fatty acids across the mitochondrial inner membrane for β-oxidation. This process is essential for energy production, particularly under conditions of elevated metabolic demand such as exercise.

• Mitochondrial β-Oxidation Enhancement: By facilitating fatty acid import, L-carnitine enhances β-oxidation and energy production while buffering excess acetyl-CoA to maintain metabolic flexibility.

• Antioxidant Properties: L-carnitine exerts antioxidant effects mediated through the upregulation of superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase, helping to mitigate reactive oxygen species (ROS) and preserve mitochondrial integrity.

• Anti-Inflammatory Modulation: L-carnitine suppresses pro-inflammatory cytokines such as TNF-α and IL-6, interrupting the feedback loop between oxidative stress and chronic inflammation.

• Fuel Switching Regulation: Carnitine biosynthesis is essential for metabolic flexibility, allowing organisms to shift between carbohydrate and fatty acid metabolism in response to environmental changes.

Chemical & Physical Specifications

Accurate characterisation of L-Carnitine 200mg research peptide is essential for reproducible experimental design.

Reconstitution & Handling Protocol for L-Carnitine 200mg

Proper reconstitution of L-Carnitine 200mg research peptide is critical for maintaining its structural integrity and biological activity.

Step 1 – Preparation

• Bring the sealed L-Carnitine vial and your chosen diluent (sterile bacteriostatic water or sterile PBS, pH 5‑7) to room temperature. Condensation can degrade the lyophilised powder.

• Clean your work surface with 70% ethanol and lay out sterile syringes, alcohol wipes and a clean work mat.

Step 2 – Vial Sanitisation

• Wipe the rubber stopper of the L-Carnitine vial with a fresh 70% ethanol wipe. Allow the alcohol to evaporate completely before piercing.

Step 3 – Reconstitution

• Draw your desired volume of diluent into a sterile syringe. A common starting concentration for research applications is 200 mg per 2 mL of diluent, yielding a 100 mg/mL stock solution.

• Insert the needle and slowly inject the diluent against the inner glass wall. Do not spray directly onto the lyophilised powder.

• Gently swirl the vial until the solution is clear and fully dissolved. Do not shake vigorously, as shaking can cause denaturation.

Step 4 – Aliquoting & Storage

• Immediately after dissolution, aliquot the reconstituted L-Carnitine into single‑use sterile vials.

• Store aliquots at –20°C. Avoid repeated freeze‑thaw cycles, as peptides are susceptible to degradation.

• Once thawed, store at 2‑8°C and use within a short period.

Concentration Reference Table

Adjust diluent volume based on your experimental requirements. For cell culture applications, typical working concentrations may range from 0.1‑10 mM.
