What is the charge on the tetrapeptide lys-lys-his-glu at ph 7?…
Answered by Deleted
Answer: The charge on peptide chain lys-lys-his-glu at pH 7 is +1.Explanation: A peptide chain is the chain formed from the condensation of two amino acids releasing molecule and forming N-terminal(Nitrogen- end) and C-terminal(Carboxyl-end). The bonds formed are known as peptide bonds.Here 4 amino acids join together forming a peptide chainIn this peptide chain N-terminal is from lysine (lys) and C-terminal is from Glutamic acid (Glu).At pH=7,The carboxyl (-COOH) groups will be deprotonated that means they will not have H-atoms and have (-1) charge.The Amino () groups will be protonated that means they have H-atoms and have (+1) charge.So, there are 3 amino groups present each having (+1) charge and 2 carboxyl groups each having (-1) charge.Total charge on peptide chain = = +1
