The isoelectric point of tyrosine is around pH 5.66. At this pH, tyrosine carries no net electrical charge. This affects its chemical properties by making it less soluble in water and more likely to interact with other molecules through hydrogen bonding.
The isoelectric point of lysine is approximately 9.74.
The isoelectric point of a molecule is determined by calculating the average of the pKa values of its ionizable groups. This involves identifying the acidic and basic groups in the molecule, determining their pKa values, and then averaging them to find the isoelectric point.
At the isoelectric point, the compound is neutral and does not exhibit acidic or basic properties. As NaHCO3 is a salt, its pH at the isoelectric point would be around 7, which is neutral. At this point, the concentration of H+ ions equals the concentration of OH- ions.
The isoelectric point graph shows how a molecule's charge changes in different pH environments. At the isoelectric point, the molecule has no net charge and is least soluble. Above the isoelectric point, the molecule is negatively charged, and below it, the molecule is positively charged. This information helps understand how the molecule interacts with its environment at different pH levels.
