您要查找的是不是:
- 在等电点pH时,有多大比例的丙氨酸是完全不解离的?说明理由。What fraction of alanine is in the completely uncharged form at its pI? Justify your assumptions.
- 在pH值为5.97时,基团不带电,并且不能在电场中迁移。这是它的等电点,缓冲能力达到最小值。At pH 5.97 the group has no net charge and will not migrate in an electrical field. Here at the isoelectric point, buffering is minimal.
