Description

L-isoleucine is a white crystalline small sheet or crystalline powder. L-isoleucine has a slightly bitter taste, is odorless, and has a sublimation temperature of 168-170℃. L-Ile is an essential amino acid and is necessary for the normal development of infants and the nitrogen balance of adults.

Advantages:

Essential amino acids: The human body cannot synthesize L-Ile. L-isoleucine must be obtained through diet or supplements and is crucial for growth and development as well as immune function.
Protein synthesis: L-isoleucine, as a branched-chain amino acid (BCAA, in synergy with leucine and valine), promotes muscle protein synthesis and reduces muscle breakdown after exercise.
Energy metabolism: L-isoleucine is involved in gluconeogenesis and fat metabolism, helping to maintain stable blood sugar levels, and is particularly suitable for energy supply during endurance sports.
Immune function: L-Ile supports the generation of antibodies and immune cells, enhancing resistance.

Application

Nutritional fortifier
L-isoleucine added to infant formula milk powder, protein powder, nutrition bars, and special medical foods (such as postoperative recovery formulas) can supplement essential amino acids and improve the nutritional value of proteins (for example, when combined with cereal protein, it can make up for the deficiency of lysine).
Sports nutrition products
L-isoleucine is added to sports drinks, protein powders and energy gels to delay exercise fatigue and accelerate muscle repair.
Flavor enhancer
L-isoleucine works in synergy with sodium glutamate to enhance the umami and rich flavors of meat and soup bases. It can be added to ready-to-eat meals, condiments and puffed foods.
Special dietary food
L-isoleucine helps control blood sugar fluctuations by regulating glucose metabolism. In low-allergy infant food, free isoleucine is added to the hydrolyzed protein formula to reduce allergenicity and ensure nutrition.
Fermented food
L-isoleucine is used in the production of soy sauce and monosodium glutamate to enhance the metabolic efficiency of bacterial strains.
