Pharmaceutical Chemistry
L-Isoleucine
Formula:
C₆H₁₃NO₂
GOST/CAS:
CAS 73-32-5
L-Isoleucine (highly purified branched-chain essential amino acid — BCAA) is a vital component that acts as a key agent for protein synthesis, blood sugar regulation, and energy metabolism support within the body. The product is a white or almost white crystalline powder or flakes, sparingly soluble in water. Due to strict purity control and the absolute absence of foreign impurities, this pharmaceutical grade of L-Isoleucine is indispensable for the production of infusion solutions, parenteral nutrition, dietary supplements, and finished dosage forms (FDF).
Applications
Pharmaceutical Industry: Used as a core component in the formulation of complex solutions for parenteral (intravenous) nutrition and infusion therapy. It is an essential ingredient in medications designed for liver function recovery and the treatment of hepatic encephalopathy.
Dietary Supplements & Sports Nutrition: Serves as a mandatory element in classic BCAA complexes (alongside leucine and valine). It is widely utilized in capsules, tablets, and powders to support muscle mass preservation, accelerate tissue recovery, and enhance physical endurance.
Infant & Specialized Nutrition: Incorporated into hypoallergenic and specialized medical formulas for newborns, as well as clinical nutrition for patients recovering from major surgeries or severe trauma.
Cosmeceuticals & Biotechnology: Applied as a nutrient substrate in cell cultures for microbiological synthesis, as well as an active ingredient in premium cosmetic products for skin regeneration and hair structure strengthening.
Key Advantages
Pharmaceutical Purity (Ph. Eur. / USP): Subject to rigorous quality control regarding heavy metals, related amino acids, and endotoxins. This guarantees absolute safety for both enteral and parenteral administration.
High Bioavailability: The native L-form of the amino acid is easily absorbed by the body, instantly integrating into metabolic pathways and muscle protein synthesis.
Formulation Stability: Demonstrates excellent compatibility with other amino acids, vitamins, and excipients. It maintains highly stable physical and chemical properties across a wide pH range.
Eco-Friendly & Safe: Produced via a microbiological synthesis (fermentation) process from plant-based raw materials. It is hypoallergenic, non-toxic, and fully compliant with strict international environmental standards.
