WebHigh levels of palmitate are expected to increase acetyl-CoA content and the NADH/NAD + ratio. In mitochondria, the increased acetyl-CoA would promote acetylation while the increased NADH/NAD + ratio would compromise the activity of the primary mitochondrial deacetylase, sirtuin 3 (SIRT3), which uses NAD + as a cofactor 24.
