Nutritional Supplement

L-Isoleucine is considered a nutritional supplement that may improve central and muscular fatigue.
It can increase the serum concentration of fatigue substances, energy metabolites, and muscle soreness substances.

Livestock and Fish Growth

Supplementing L-isoleucine in the diet may improve the growth performance of livestock and fish, such as pigs, laying hens, and juvenile Jian carp.

Essential Amino Acid

L-Isoleucine is an essential amino acid that cannot be synthesized by the body and must be obtained from the diet.
Benefits may include regulating blood glucose, participating in hemoglobin synthesis, and reducing post-workout fatigue.

Role in Protein Metabolism

L-Isoleucine can regulate protein metabolism, enhance immunity, and improve animal fertility.

Industrial Uses

L-Isoleucine is widely used in food, medicine, cosmetics, feed, and other industries, showing significant commercial value and broad developmental prospects.
Corynebacterium glutamicum is one of the major strains used for L-isoleucine production.

Biosynthetic Pathway

The biosynthetic pathway of L-isoleucine in Corynebacterium glutamicum involves 10 reaction steps originating from L-aspartate. Key genes in this pathway, such as ilvA and ilvBN, are strictly regulated.

General Description

L-Isoleucine, also known as Isoleucine, is an essential amino acid that is crucial for protein synthesis and muscle repair in the body. It is classified as a branched-chain amino acid (BCAA) and is commonly found in high-protein foods such as meat, fish, eggs, and dairy products. L-Isoleucine is involved in regulating blood sugar levels and providing energy to the muscles during physical activity. It also plays a role in the production of hemoglobin and can help improve overall endurance and recovery after exercising. Additionally, L-Isoleucine is important for maintaining proper nitrogen balance in the body and is often used in supplements to support muscle growth and athletic performance.
