What aspects of amino acid structure vary among different amino acids? select one: a. the presence of a central c atom b. the glycerol molecule that forms the backbone of the amino acid c. the long carbon-hydrogen tails of the molecule d. the components of the r-group?

 amino acid formula  NH2 - CH -COOH , in general
                                                 l
                                                R
What is going to be different  this is R

the answer
d). the components of the r-group

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
