The structure molecule shown above is a two-ringed structure with an asymmetric carbon in the glutarimide ring. The molecular formula is and its molecular weight equals to 258.2. The ingredients of each capsule of Thalomid include anhydrous lactose, microcrystalline cellulose, polyvinylpyrrolidone, stearic acid, colloidal anhydrous silica, and gelatin. The nearly odorless crystalline powder is soluble at 25 degrees Celsius in dimethyl sulfoxide and sparingly soluble in water and ethanol. The color of the powder is white to off-white.
Many organic compounds exist as a combination of their enantiomers.
Enantiomers are compounds with identical chemical composition that are, at a molecular level, mirror images of each other. The enantiomers, therefore, have the same type and number of atoms and chemical compounds, but have opposite three-dimensional configurations. A frequently used analogy is the symmetry of the left and right hands. In nature compounds exist as a combination of their enantiomers, but only one may be physiologically useful. Terator is a Greek word that means monster.
