keto-amino acids

YUAN Wei-jie · FDA-approved active Small molecule

Keto-amino acids provide nitrogen and carbon skeletons for protein synthesis while reducing the nitrogen load in patients with renal or hepatic impairment.

Keto-amino acids provide nitrogen and carbon skeletons for protein synthesis while reducing the nitrogen load in patients with renal or hepatic impairment. Used for Chronic kidney disease with hyperazotemia (to reduce protein catabolism and nitrogen accumulation), Hepatic encephalopathy (to reduce ammonia-generating amino acid load), Protein-energy malnutrition in renal failure.

Mechanism of action

Keto-amino acids (the α-ketoacid analogs of essential amino acids) are metabolized to their corresponding amino acids through transamination, allowing protein synthesis without accumulating excess nitrogen. This is particularly useful in chronic kidney disease and hepatic encephalopathy, where nitrogen retention is problematic. The α-ketoacid forms reduce the dietary protein burden while maintaining amino acid availability.
