An amino acid has the form shown at
R-CH-C-O^- (with a NH2 bonded to the CH and a O double bonded to the C) (O^- means the C has a negative charge)
a) a pH of 7.0
b) any pH other than 7.0
c) a pH greater than its isoelectric point
d) its isoelectric point
e) a pH less than its isoelectric point
Would it be "c"?
