dl-glutamine

DL-Glutamine (2-amino-4-carbamoylbutanoic acid), a non-essential amino acid, exists abundantly throughout the body and is participated in many metabolic processes. It is synthesized from glutamic acid and ammonia, and is the main carrier of nitrogen in the body and is an important energy source for many cells.

L-Glutamine (L-Glutamic acid 5-amide) is a non-essential amino acid that exists in large quantities in the human body and participates in many metabolic processes. L-Glutamine provides a carbon source for oxidation in certain cells.

D-Glutamine is the D-type stereoisomer of cell-permeable glutamine, one of the 20 amino acids encoded by the standardized genetic code.
