What is the predominant form of the amino acid abbreviated R at pH 7? a.The protons in the C terminal and in the acidic side chains dissociate at pH lower than 7. This leaves a negative charge from each of those substituents. Meanwhile, the protons in the N terminal and those of the basic side chains dissociate at pH above 7.What Is The Charge On The Tetrapeptide Lys-lys-his-glu At PH 7?

Answer: The charge on peptide chain lys-lys-his-glu at pH 7 is +1.Explanation: A peptide chain is the chain shaped from the condensation of 2 amino acids releasing molecule and forming N-terminal((*7*)- finish) and C-terminal(Carboxyl-end). The bonds shaped are referred to as peptide bonds.Here Four 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 might be deprotonated that means they will no longer have H-atoms and feature (-1) charge.The Amino () teams can be protonated that implies they have got H-atoms and feature (+1) charge.So, there are 3 amino teams present each and every having (+1) charge and a couple of carboxyl teams each having (-1) charge.Total charge on peptide chain = = +1
