It is also a cofactor for two key mitochondrial enzymes essential to energy production, the conversion of pyruvate to acetylcoenzyme A (CoA), and the alpha-ketoglutarate dehydrogenase complex, which catalyzes the conversion of alpha-ketoglutarate to succinyl CoA, both important reactions in the citric acid (Kreb's) cycle.

It has also been shown that the AD brain has decreased activity of pyruvate dehydrogenase complex which generates acetyl-CoA, the precursor of acetylcholine from pyruvate [41, 42], decreased activity of phosphofructokinase [43], and alpha-ketoglutarate dehydrogenase [44] but increased cerebral release of ammonia and amino acids [39, 40].
