L-glutamine is a protein-forming amino acid that the body can normally produce itself. Particularly large amounts of glutamine are found in muscle. It is also found in numerous protein-rich foods.
In metabolism, glutamine is an important carrier of nitrogen. It is involved in the formation and breakdown of other amino acids and in various synthesis processes. Glutamine and glutamate are closely related, but have different chemical properties.
Amino acids differ in whether the human body can produce them itself. As components of proteins, many occur in protein-rich foods; some are also needed for other compounds produced by the body. The combination of different amino acids also influences the amino acid pattern of a food.
With amino acid preparations, it is worth looking at the actual form of the raw material. A free amino acid and its hydrochloride salt do not have the same chemical weight; the amounts may therefore differ. Different tablet or powder products, too, can only be compared meaningfully on the basis of the nutrient table.
