9. What does a reducing agent such as beta-mercaptoethanol OH-CH2-CH2 -SH do in the process of straightening curly hair? 10. Think about the changes of ionization state of amino acids in general and more specific the amino acid Histidine at different pH. The charge in this residue depends on the environment. How can a protein act as a buffer in the cell?

Incorrect Question 16 0/1 pts This amino acid is +H3N—CH-0-0 CH2 CEO neutral aspartic acid. aspartic acid at its isoelectric point. aspartic acid at a pH that is lower than the isoelectric point. aspartic acid at a pH that is higher than the isoelectric point. Reconsider your answer! Since the nitrogen atom has a positive charge and both carboxylic acid groups have lost a hydrogen atom, this amino acid must be at its isoelectric point.
