Morphology and its properties D-isoleucine is a white crystalline powder, D-isoleucine is a very stable compound with the following characteristics: Optical activity: D-isoleucine is an optical isomer with an optical rotation of +13.8° (c=2, aqueous solution). This optical activity is due to the chiral selectivity between the D-isomer and the L-isomer. Solubility: The solubility of D-isoleucine in water is low, about 22g/L, but it has a high solubility in polar solvents such as ethanol and acetone. Chemical properties: D-isoleucine is an amino acid with amino and carboxyl groups, which can undergo acylation, esterification, sulfonation, and other reactions with other compounds. In addition, D-isoleucine can experience a ring-opening response in the presence of sodium hydroxide to generate β-isoleucine butyric acid. Biological activity: D-isoleucine has critical physiological functions in the living body, such as enhancing the resistance of the living body, improving cardiovascular function, and improving the body's metabolism. D-isoleucine is a stable compound with properties such as optical activity, low water solubility, various chemical reactivities, and important biological activities. These characteristics provide the basis for its application in medicine, food, the chemical industry, and other fields. |
