L- Isoleucine belongs to the group of branched amino acids, commonly known as BCAA. This group also includes such amino acids as valine and leucine.
These amino acids have an important energy function that allows the athlete to protect the muscles from disintegration. This process involves using blood sugar in the first attempt. When this sugar is gone, the body wants to get extra energy from stored glycogen stores in the muscles and liver. When the carbohydrate resources are significantly depleted, the body is forced to use the energy that it can get from the muscle tissue to continue the effort. In this situation, the body absorbs the BCAA amino acids from the muscles that are capable of converting to glucose in the process of gluconeogenesis, so that the body can continue the effort. To prevent muscle catabolism, use a supplement containing isoleucine, leucine and valine. Supplementation, such as Isoleucine has a similar effect on 3-hydroxy-3-methylbutyric acid. It is involved in the inhibition of harmful catabolic reactions and also stimulates anabolic reactions. In addition, the leucine isomer supports protein synthesis in muscle tissue and in the liver.This amino acid also plays an important role in tissue regeneration. This property is very useful in the event of an injury or illness that causes the body to become weak and tired, and needs the necessary nutrients.
