Concept 4.3 A small number of chemical groups are key to the functioning of biolo
8. Here is an idea that will recur throughout your study of the function of molecules: Form Follows Function. You see this in enantiomers, you will see recurpthroughout your study of theow we are molecules
9. Here is an idea that will it in roteins and enzymes, and n function of going to look at testosterone and estradiol. Notice how similar these two molecules are, and yet it in prot structure, change the function. You see this in enantiomers, you will see you know that each has a vand now we are ffect. Lto look at testosterone and sketch below, and similar th astly different e going abel each molecule in the estradiol. Notice how circle the differences. are, and yet you know what a vastly different effect each has. Label each molecu

and circle the differences.
