Handedness Right and left hands are not identical Right and left hands are mirror images of each other they are nonsuperimposable mirror images Almost all the molecules in the human body are handed Handedness primarily arises from the tetrahedral stereochemistry of sp3-hybridized carbon atoms Handedness is crucial to understanding biological chemistry Left hand Right hand Right and left hands are not identical ▪ Right and left hands are mirror images of each other – they are nonsuperimposable mirror images ▪ Almost all the molecules in the human body are handed ▪ Handedness primarily arises from the tetrahedral stereochemistry of sp3 -hybridized carbon atoms ▪ Handedness is crucial to understanding biological chemistry Handedness
