Overview of natural metabolic pathways that can be harnessed for the conversion of glucose to valuable aromatic and aliphatic aldehydes through carboxylic acid intermediates based on E. coli metabolism. Aldehydes can also be obtained from the 2-keto acid pathway (35, 55), terpenoid pathways (54), and other pathways. TCA, tricarboxylic acid.
