What is the approximate net charge, to the nearest integer value, of glycine, aspartic acid, lysine, and histidine at:
Thanks for letting me work on your post. Here is my explanation:
For glycine, pk1=2.34, pk2=9.6
at pH=1.0, the net charge is +1;
at pH=3.0, the net charge is 0;
at pH=5.0, the net charge is 0;
at pH=7.0, the net charge is ...
