Answer:
Polar, nonpolar,polar acidic group R,hydrogen,outer surface,hydrophilic,water and inside.
Step-by-step explanation:
Glutamate is a polar acidic amino acid, whereas proline is non polar. The polar acidic group R of glutamate may form hydrogen with another amino acid R group. Glutamate may also move to the outer surface of the protein where it would form hydrophilic interactions with water. However, proline would move to the inside of the protein.
