Abstract:
The functionalization of peptides and proteins by aldehyde or keto groups has become the subject of intensive research since the discovery of the inhibition properties of peptide aldehydes and the advent of protein engineering. The first part of this review focuses upon the tremendous efforts devoted to the solid-phase synthesis of peptide aldehydes as protease inhibitors. The second part describes the utility of the aldehyde or keto functionalities for the site-specific modification of peptides or proteins.

Nucleophilic Addition to the Carbonyl Group: General Mechanism
A stronger nucleophile can directly attack the electrophilic center, the carbonyl carbon. The HOMO orbital of the nucleophile interacts with the LUMO (π* antibonding) orbital present on the carbonyl carbon. This interaction breaks the π bond and shifts the π bonding...
