compound amino acid (19) + alanyl-glutamine

Compound amino acid (19) + alanyl-glutamine is a specialized parenteral nutrition formulation developed by the Institute of Radiation and Radiation Medicine at the Academy of Military Medical Sciences in China. It consists of a balanced mixture of 19 essential and non-essential amino acids (specifically the 19AA-I formulation) supplemented with the stable dipeptide alanyl-glutamine. This combination is designed to provide a high-quality nitrogen source for patients in severe catabolic states, such as those following major trauma, surgery, or burns. Alanyl-glutamine serves as a stable precursor to L-glutamine, an amino acid that becomes conditionally essential during critical illness to support the immune system, maintain intestinal mucosal integrity, and preserve muscle mass. The product is administered intravenously to maintain nitrogen balance and promote recovery in patients who cannot receive adequate enteral nutrition.
