Mitochondrial FA shuttle.
L-Carnitine is a small molecule essential for mitochondrial fatty acid β-oxidation — specifically for the transport of long-chain fatty acyl-CoAs across the inner mitochondrial membrane. Though endogenously synthesized, it is studied extensively as a supplemental compound. Supplied as research-grade material with 3rd-party HPLC verification and full Certificate of Analysis per lot.
L-Carnitine is a small molecule essential for mitochondrial fatty acid β-oxidation — specifically for the transport of long-chain fatty acyl-CoAs across the inner mitochondrial membrane. Though endogenously synthesized, it is studied extensively as a supplemental compound.
L-carnitine functions as a substrate for carnitine palmitoyltransferase I (CPT-I), which converts long-chain acyl-CoAs to acyl-carnitines for mitochondrial import. Without carnitine, long-chain fatty acid oxidation cannot proceed — a genetic block (primary carnitine deficiency, CPT-II deficiency) is a well-characterized metabolic disease.
Several L-carnitine products are FDA-approved for primary carnitine deficiency (Carnitor). Widely studied in cardiovascular, metabolic, and muscle disease research. Generally recognized as safe at supplemental doses; research-grade material is for non-clinical research.
The above summarizes published research literature. This is not medical advice, a protocol, or a recommendation for use. This compound is supplied for laboratory research only.
L-Carnitine is a small molecule (molecular formula C7H15NO3, MW approximately 161.2 Da) — not a peptide.
The full structural data and release specifications are in the Compound Profile section above. Every lot ships with an independently verified Certificate of Analysis.
Each lot is independently verified by a 3rd-party analytical laboratory (STERIS Labs, Alcami Analytical, or equivalent) before release. Release specification is HPLC purity ≥ 99.5% (typical > 99.8%), mass spectrometry identity match within ±0.5 Da, water content < 5.0% Karl Fischer, and endotoxin < 0.25 EU/mL by LAL (USP <85>).

All compounds ship at ambient temperature in discreet, tamper-evident packaging. Lyophilized peptide powder is stable at room temperature for typical transit windows, which is why research-grade vendors ship this way. Tracked; signature not required.
Store unopened lyophilized product at 2–8°C protected from light. Once reconstituted, most peptides are stable at 2–8°C for approximately 28 days (compound-dependent).
Several L-carnitine products are FDA-approved for primary carnitine deficiency (Carnitor). Widely studied in cardiovascular, metabolic, and muscle disease research. Generally recognized as safe at supplemental doses; research-grade material is for non-clinical research.
All PeptideBros compounds are sold strictly as chemical reference materials for in-vitro laboratory research. They are not for human consumption.
HPLC-verified. Mass-spec confirmed. Ambient-stable transit. The paperwork other vendors hope you never ask for.
