What are amino acids?
The amino acids that make up proteins are in fact divided into groups, depending on whether our body is able to synthesise them on its own or not - which means that they must be supplied externally. The amino acids belonging to the first group are called endogenous and those belonging to the second group are called exogenous, i.e. essential. Glutamine belongs to the former group of amino acids; the body is able to synthesise it from other amino acids.
Glutamine and the development of muscle mass
From the point of view of muscle mass development, the availability of essential amino acids is of primary importance. We already know that glutamine does not belong to this group, but does this mean that its consumption does not affect muscle protein synthesis? In fact, if we take a look at the results of scientific studies, we will find that they provide encouraging conclusions.
Glutamine and muscle catabolism
Research also shows that glutamine's action is particularly unique in terms of its effect on muscle catabolism. This amino acid protects muscles from proteolysis associated with, for example, physical exertion. This amino acid shows some anti-catabolic potential, which is protective for gained muscle mass.
Other benefits of glutamine
In many cases, this amino acid could prove to be a potentially valuable addition to the diet. It is worth knowing that a significant portion of the ingested glutamine is captured by the cells of the small intestine. Although at first glance this appears to be a disadvantage of the resource in question, in reality it is not. Glutamine, which is the primary and priority fuel for enterocytes, can affect the condition of the intestinal epithelium.
