Decarboxylases are known for their roles in a wide variety of catabolic and anabolic pathways, including decarboxylation of a- and p-keto acids, amino acid conversions, and carbohydrate biosynthesis. Mechanistically, a decarboxylation has parallels to retro-aldol cleavage reactions (Figure 1.32). [Pg.26]

Cleavage reactions of carbohydrates also occur on treatment with aqueous base for prolonged periods as a consequence of base catalyzed retro aldol reactions As pointed out m Section 18 9 aldol addition is a reversible process and (3 hydroxy carbonyl com pounds can be cleaved to an enolate and either an aldehyde or a ketone...
