Lysine charge at ph 2

Web2 iul. 2024 · Lysine with its lysyl ((CH 2) 4 NH 2) side chain is a basic and positively charged amino acid at physiological pH. WebThe cell lysis activities of these peptides could be increased up to four times as the solution pHs dropped from pH=7.4 to pH=5.5. The pH sensitivity of a histidine-containing peptide was determined by histidine substitution numbers. Peptide derivatives with more histidines were associated with increased pH sensitivity.
