The two enantiomers of Thalidomide can and do interact metabolically different.

The two enantiomers of Thalidomide can and do interact metabolically different. In the case of Thalidomide, it was discovered that only one of the two enantiomeric forms was responsible for the mutagenic effects seen. Chapter 5 The Structure and Function of Macromolecules.

Quantitation of Methemoglobin

Quantitation of Methemoglobin. Methemoglobin. Methemoglobin (Hi) is a form of hemoglobin In which the ferrous ion( Fe 2+ ) has been oxidized to the ferric state(Fe 3+ ) and is, therefore, incapable of reversibly combining with oxygen (and, therefore, cannot transport the oxygen molecule). .
