Web31 aug. 2024 · Lysine is also an amino acid . It has both acidic and basic group . The pka value of its basic side chain is 10.5 . Hence at pH more than it it is neutral or have no charge but at pH value less than 10.5 , it acquires H⁺ ion and becomes positively charged. Hence at pH value of 9.5 which is less than 10.5 , it will be positively charged . Web16 apr. 2024 · Lysine; These basic amino acids are so classified because they have basic side chains containing nitrogen, which resemble ammonia (a base). The pKa values of basic amino acids are high enough to bind protons and give them a positive charge.
