What is L-Isoleucine ?
L-Isoleucine is also called "isoleucine" and the system name is "α-amino-β-methylvaleric acid". L-Isoleucine powder is one of the essential amino acids for human body, belonging to a kind of aliphatic neutral amino acids. Rhombic leaf-like or flaky crystals, bitter in taste. Soluble in water.
There is more content in meat. There are two asymmetric carbon atoms in a. So there are four stereoisomers. It exists in various protein, but D- isoleucine does not exist in protein. It is one of the essential amino acids, and it is nutritionally related to valine and leucine with similar structures. Although it is a sugar amino acid, it is slightly ketogenic. A- methylbutyryl-CoA, which is generated by amino transfer and decarboxylation from L-Isoleucine in organisms, undergoes similar fatty acid decomposition to generate acetyl-CoA and propionyl-CoA, which become succinyl-CoA and enter the citric acid cycle.
When synthesized by bacteria, it is known that they are composed of threonine and pyruvate dihydroxy acid →a- keto acid.
L-Isoleucine powder is an essential amino acid for human body and one of the three branched-chain amino acids. Because of its special structure and function, A plays a particularly important role in human life metabolism. It is mainly used to prepare compound amino acid preparations, especially for high branched chain amino acid infusion (such as 3H infusion) and oral liquid (Gan 'angan syrup, etc.).

What is the main function of L-Isoleucine ?
The function and efficacy of isoleucine include promoting protein synthesis, enhancing immunity, relieving fatigue and maintaining acid-base balance.

1. Promote protein synthesis.
L-Isoleucine powder can participate in the anabolic process of protein, improve the activity of ribosomes in cells, and thus promote the synthesis of protein.
2. Enhance immunity
It can help to regulate the activity of the immune system, enhance the immune function of the human body and improve the body's disease resistance.
Step 3 relieve fatigue
It can help speed up the conversion of glucose into energy and reduce the accumulation of lactic acid, thus helping to relieve fatigue.
4. Maintain acid-base balance
L-Isoleucine powder is beneficial to maintain the osmotic pressure and acid-base balance in the human body, thus playing a role in maintaining acid-base balance.
In our daily life, we need to pay attention to proper aerobic exercise, such as playing Tai Ji Chuan and basketball, which can help to strengthen our physique. We also need to pay attention to developing good eating habits. We can properly eat fresh vegetables and fruits, such as carrots and apples, which can provide energy for the human body.
