This nitrogen atom contains a lone pair of electrons that enables it to act as a nucleophile

Contributing factors include: reduced nutritional intake (proteins, essential amino acids, competition between amino acid transporters, vitamin insufficiency [riboflavin: GSSG reductase, nicotinic acid: NADPH, pyridoxine (B 6 ): SAMe pathway], mitochondrial dysfunction: ATP deficiency, down regulation SAMe synthase, oxidation of SAMe pathway enzymes, enhanced GSH utilization: conjugation reactions (toxins, drugs), and overwhelming oxidative challenge

Specifically, small apoAI containing HDL particles are the most efficient at accepting lipid hydroperoxides, which are reduced to their inactive lipid hydroxides via oxidation of the methionine residues in apoA-I (850)

The AMPK activator metformin inhibits mTOR signaling and promotes oxidative metabolism over glycolysis
