Description

L-leucine is an essential amino acid with the chemical formula C6H13NO2. It is the corresponding isomer of D-leucine and is a white lustrous hexahedral crystal or white crystalline powder at room temperature. Odorless and slightly bitter. Sublimation occurs at 145-148℃. Melting point: 293-295℃ (decomposition). It is stable in performance in inorganic acid aqueous solutions in the presence of hydrocarbons. Slightly soluble in ethanol (0.07%), soluble in dilute hydrochloric acid and alkaline hydroxide and carbonate solutions. Insoluble in ether.

Advantages:

Essential amino acids:
The human body cannot synthesize them by itself and must be obtained through diet or supplements.
Promoting protein synthesis:
L-leucine, as the core component of branched-chain amino acids, directly stimulates muscle growth and repair.
Regulating metabolic functions:
L-leucine is involved in gluconeogenesis and energy metabolism, helping to maintain blood sugar balance.

Application

Sports nutrition and functional foods:
L-leucine is used in protein powder, energy bars, sports drinks, etc. Quickly replenish muscle loss after exercise, reduce catabolism, and enhance endurance recovery. L-leucine, when combined with isoleucine and valine, has become a standard ingredient for fitness enthusiasts.
Food flavor enhancers and flavoring agents:
L-leucine combines with sodium glutamate to enhance the umami flavor layers of meat, soups and seasonings. L-leucine is used in soy sauce, condiments and instant noodle soup packets to reduce sodium content while maintaining flavor. L-leucine mimics the aroma of meat in plant-based meat products and enhances the taste of vegetarian products.
Special Diets and Healthy Foods:
L-leucine is added to oral nutritional supplements or liquid foods to maintain muscle mass and prevent malnutrition. L-leucine is a meal replacement food for diabetic patients, which helps regulate blood sugar fluctuations.
Weight management and meal replacement products:
L-leucine can be used in meal replacement shakes, high-protein snacks and low-calorie beverages.
Infant and toddler food:
L-leucine, as an essential amino acid additive in infant formula milk powder, ensures the needs of growth and development.
Animal nutritional fortification:
L-leucine is added to livestock and poultry feed to enhance protein utilization and promote growth (such as in pig and poultry farming).
Aquaculture:
L-leucine is used to enhance the stress resistance of fish and shrimp and improve the meat quality.
