How to calculate net charge of amino acids
WebThe three amino acids are Lysine, Arginine, and Histidine, and how I remember these three is using the abbreviation for the strong base LAH (lithium aluminum hydride). They are basic because their side chain is basic and are positively charged at pH values below their pKa’s. WebTo calculate the charge at different pH: At pH 3 K, R, H are + and D,E have no charge so add up all of the K,R,H in the sequence and that is your net charge at pH 3 At pH 6 K, R, H are + but now D,E are (-) so subtract one total from the other to figure if …

These groups have opposite charges; the carboxyl group is acidic and the amine group is basic. When the pH of a solution equals the pI of an amino acid, the two groups cancel each other out and the amino acid has no net charge. To calculate …
