    Product Description

    D-Carnitine is an isomer of the conditionally essential nutrient L-carnitine (Item No. 21489), which facilitates long-chain fatty acid transport into the mitochondrial matrix for β-oxidation.1 It inhibits the uptake of L-carnitine by rat kidney brush border membrane vesicles when used at a concentration of 50 µM and by primary human limbal corneal (HCLE) and conjunctival epithelial (HCjE) cells when used at 0.5 and 1 mM.2,3

    WARNING This product is not for human or veterinary use.
