Debenedetti, Princeton University, Princeton, NJ, and approved November 17, 2020 (received for review April 9, 2020) Redox biochemistry plays a key role in the transduction of central metabolic redox substrates (3). In addition, since its chemical energy in living systems. However, the compounds standard potential is ∼100 mV lower than that of the typical observed in metabolic redox reactions are a minuscule fraction aldehyde/ketone functional group, it effectively decreases the of chemical space. It is not clear whether compounds that ended steady-state concentration of potentially damaging aldehydes/ up being selected as metabolites display specific properties that ketones in the cell (3).
