Abstract

We studied the role of the D-amino acids (D-aa) D-serine, D-alanine, D-methionine, D-aspartate, D-tyrosine and D-arginine on rat liver mitochondria. The stability of D-amino acids, mitochondrial swelling, transmembrane potential and oxygen consumption were studied under oxidative stress conditions in rat liver mitochondria. In the presence of glutamate-malate all D-aas salts increased mitochondrial swelling, while in the presence of succinate plus rotenone only D-ala, D-arg and D-ser, induced mitochondrial swelling. The transmembrane potential (ΔΨ) was decreased in the presence of 1 μM Ca²⁺. The D-aas inhibited oxygen consumption in state 3. The D-aa studied exerted effects on mitochondria via an increase of free radicals production.
