Skip to 0 minutes and 14 seconds This picture is a summary of the role that glutamine plays in nucleic acid. You can see from this chart. Glutamine is a composition of protein and it is able to promote the composition of protein. What’s more, it can transport nitrogen for discharge or transport nitrogen to other substances in order to transform into other substances containing nitrogen. It can also be used for glycogenesis when our body needs glucose. As the precursor of antioxidant, it promotes antioxidant capacity inside the body. Through discharging or transporting the amidogens, it also promotes the acid-base equilibrium in the body. Additionally, it is the main energy source for fast-division cells, such as intestinal cells or immunocyte cells.

Skip to 1 minute and 19 seconds Glutamine can maintain the normal function of intestinal cells and it also helps the activation of immunocyte cells. Previous studies have shown that glutamine level will decrease when our body is in traumatic or under metabolism stress condition. Under these stress conditions, the glutamine level in body fluid or body tissue will decrease. The amount of glutamine decrease is related to the recovery rate from trauma or diseases. Low glutamine level represents poor recovery rate and high mortality rate. In other words, if we could enhance the glutamine level in our body, it could possibly help increase recovery rate. Therefore, glutamine can also become an indicator of conditional essential amino acids.

Skip to 2 minutes and 22 seconds As we mentioned that glutamine is non-essential amino acids, our body could synthesis on its own. But under certain specific condition, such as traumatic stress, infection or post-surgery, glutamines will become an essential amino acid. So glutamine is a conditional essential amino acid. The supplementation of glutamine is not necessarily in normal circumstances. As we’ve mentioned, it exists in protein and the amount of glutamine could be obtained by our daily protein diets. Besides, our body could synthesis glutamine on our own. Normally, the generation and utilization of glutamine should be able to reach the balance. It is not necessary to supplement it additionally. However, it will be different from the situation of diseases. Our body’s immune function will be activated when facing disease conditions.

Skip to 3 minutes and 21 seconds Immune cells will be hugely proliferated. Activated immunocyte cells use glutamine as the source of energy. When immunocyte cells are hugely proliferated, a huge amount of glutamine is required. The amount of synthesized glutamine by our body will be insufficient for the utilization. In this way, glutamine will be in a shortage state if we don’t supply additionally.

The Role of Glutamine

Continuing on last step, Prof. Yeh will explain what other functions that glutamine serves.

As the precursor of antioxidant, it promotes antioxidant capacity inside the body. Through discharging or transporting the amidogens, it also promotes the acid-base equilibrium in the body.

Glutamine can also maintain the normal function of intestinal or we can say that it helps the activation of immunocyte. Next, she gives examples when body requires to supply glutamine. In certain conditions, such as traumatic stress, infection or post-surgery, glutamine will become an essential amino acid. And supplementation of glutamine is necessary in these cases.
