(2S,3S)-2-Amino-3-methylpentanoic acid [ 73-32-5 ]

Purity: 98% for white crystalline or crystalloid powder, odurless, taste slightly bitter. Mp284 ℃ (breakdown), 168-170 ℃ distillation. In the water solubility for 4.12%, and very difficult to soluble in ethanol and ether, [alpha] 25D + pooled (C = 0.5-2.0 g/ml, HCl in 5mol/L), [alpha] 25D + 12.4 (C = 0.5-2.0 g/ml, H2O), isoelectric pI for 6.02. Increase nutrition supplements. L - isoleucine for human body essential amino acid, every one of the lowest requirements about 0.7 g, but excessive edible and produce leu-enkephalin antagonism role exists and development. This product can strengthen various food, such as wheat flour, glutenin, peanut, potatoes and so on contained isoleucine to restrict amino acids, unsuited strengthening, the goods also with other essential amino acids were used for amino acid injection, composite amino acid as infusion of food additive, preparation and amino acid infusion. The goods are used in biochemical research, bacteriology and tissue culture.
