Medchemexpress LLC (±)-Carnitine chloride | 461-05-2 | 98.0% | 25 G
(±)-Carnitine chloride exists in two isomeric forms, D and L. L-carnitine is crucial for the β-oxidation of fatty acids and exhibits antioxidant and anti-inflammatory properties. It facilitates the shuttle of long-chain fatty acids across the inner mitochondrial membrane and enhances mitochondrial respiration. It also protects hepatocytes from H2O2-induced cell damage by activating the Nrf2 signaling pathway through Akt.
