Question:

Many organic compounds contain more than one functional group. An example is phenylalanine (shown below), one of the simple building blocks of proteins.

(a) What functional groups are present in phenylalanine?
(b) Redraw the structure, adding all unshared electron pairs.
(c) What is the molecular formula of phenylalanine?
(d) Draw another structural isomer that has this formula. What functional groups does this isomer have?
