We have incubated heart mitochondria with ferrous ions as catalyst of lipid peroxidation. Ferrous ions induced an increase of malondialdehyde formation and a reduction of mitochondrial oxygen consuming and calcium transporting capacities. L-Carnitine and Acetyl-L-Carnitine failed to prevent mitochondrial damage. Propionyl-L-Carnitine significantly improved mitochondrial function, but failed to reduce malondialdehyde formation. This protective effect was specific for Propionyl-L-Carnitine as propionic acid and L-Carnitine did not modify mitochondrial damage.

Abstract
We have incubated heart mitochondria with ferrous ions as catalyst of lipid peroxidation. Ferrous ions induced an increase of malondialdehyde formation and a reduction of mitochondrial oxygen consuming and calcium transporting capacities. L-Carnitine and Acetyl-L-Carnitine failed to prevent mitochondrial damage. Propionyl-L-Carnitine significantly improved mitochondrial function, but failed to reduce malondialdehyde formation. This protective effect was specific for Propionyl-L-Carnitine as propionic acid and L-Carnitine did not modify mitochondrial damage.File in questo prodotto:
