Many of the Reactions Studied in This Chapter Are Stereospecific

question 37

Multiple Choice

Many of the reactions studied in this chapter are stereospecific.Why are stereospecific reactions important?

• A)When a reaction produces a mixture of enantiomers,it is often very difficult to separate them.A mixture of products is often not useful.
• B)Often stereoisomers of a particular compound will have very different biological effects on an organism.Only one isomer is biologically helpful,and the other may be harmful.
• C)Often only one stereoisomer is biologically active,and coupling reactions are often used for the production of biological materials.
• D)All of the choices are true.

Mammals that are primarily adapted to living in water, including species such as whales, dolphins, and seals.

Slow Fibers

Muscle fibers characterized by their slow contraction time and enhanced ability to sustain long-term activities.

Fast (IIb) Fibers
