Alanyl-Glutamine (Dipeptiven)

L-alanyl-L-glutamine is a dipeptide used to deliver glutamine in intravenous nutrition; after major abdominal surgery, parenteral nutrition enriched with it improved nitrogen balance and lymphocyte recovery in a randomized, double-blind study of 28 patients.

Summary

L-alanyl-L-glutamine is a dipeptide used to deliver glutamine in intravenous nutrition; after major abdominal surgery, parenteral nutrition enriched with it improved nitrogen balance and lymphocyte recovery in a randomized, double-blind study of 28 patients. · pmid:9488531

In a French multicenter double-blind trial in 114 intensive-care patients, alanyl-glutamine-supplemented parenteral nutrition lowered complicated outcomes (41% against 61%), mainly infections and pneumonia, and hyperglycemia, without changing early deaths or 6-month survival. · pmid:16505644

Structure

No structure representation on record. PepJunkie draws only what an authoritative record supplies; for a peptide that is the residue sequence, and none has been curated for Alanyl-Glutamine (Dipeptiven) yet.


Dose evidence, rung by rung

No established safe human dose. Nothing on file establishes one. That is a statement about the evidence PepJunkie holds, not a promise about the molecule.
