(S)-(+)-Monosodium glutamate (MSG) is a flavor enhancer used in many foods. Some people have an allergic reaction to MSG (including headache, chest pain, and an overall feeling of weakness). Fast food often contains substantial amounts of MSG, which is widely used in Chinese food as well. (S)-(+)-MSG has a specific rotation of +24.a. What is the specific rotation of (R)-(-)-monosodium glutamate? b. What is the specific rotation of a racemic mixture of MSG?
The specific rotation of quinine, an anti-malarial drug, is -165°. How much quinine (in %) is present in a sample that has an observed specific rotation of 33°? CH3O HO H H quinine (antimalarial drug)
The specific rotation of the pure (S) form of Ivermectin is +85.0° when measured using light with a 500 nm wavelength. Ivermectin is an expensive component of a popular COVID treatment called NO-FX. To save money, the Trumpharm company makes NO-FX by mixing inexpensive racemic Ivermectin with some enantiomerically pure Ivermectin. A 1.3 g sample of NO-FX is dissolved in 6.0 mL of CHCl3. When placed in a 1 cm cell, the observed rotation at 500 nm is -0.6°. a) What is the specific rotation of the sample? b) Which isomer is in excess and how do you know it is in excess? c) What is the optical purity of the sample?
