Description

4,5-Dihydroxy-2,3-pentanedione is a carbonyl compound derived from the oxidation of ascorbic acid. It finds application in wastewater treatment and exhibits antimicrobial properties effective against infectious diseases. This compound functions by inhibiting protein synthesis through its ability to bind to the ribosome, thereby preventing the formation of peptide bonds between amino acids. Additionally, 4,5-Dihydroxy-2,3-pentanedione has been observed to interact with plasma proteins, likely due to its acyl chain structure.

The synthesis of 4,5-Dihydroxy-2,3-pentanedione involves a catalytic mechanism that utilizes dehydroascorbic acid and molecular oxygen.
