Quantity: 20Metric Tons Specs:More than 98.5% Payment Method: TT/LC L-Isoleucine CAS Number: 73-32-5 Powder tastes at first slightly C6H13NO2 Food grade amino acids L Isoleucine FCC iv L-Isoleucine CAS Number: 73-32-5 Chemical Name: (2S, 3S)-2-Amino-3 -methylpentanoic Acid Chemical Formula: C6H13NO2 Molecular Weight: 131.1700 Physical Properties: White crystals or crystalline powder; slightly bitter taste. Sparingly soluble in water L-isoleucine is one of the branched chain amino acids (L-isoleucine, L-valine, and L-leucine) and is classified as an essential amino acid. This means the body cannot manufacture L-isoleucine; it must be acquired through diet or supplementation. The male adult’s daily requirement is 10 mg per kg of body weight. Food sources for isoleucine include almonds, cashews and soy protein. Applications: L-isoleucine is commonly used in parenteral and enteral nutrition. It is used in combination with the other branched chain amino acids to improve the nutritional status of patients with hepatic diseases. BCAAs serve as important fuel sources for skeletal muscle during periods of metabolic stress; BCAAs may promote protein synthesis, suppress protein catabolism and serve as substrates for gluconeogenesis. BCAAs are catabolized in skeletal muscle, stimulating the production of L-alanine and L-glutamine, among other substances.
