Introduction-

“Since you have posted multiple questions, we will provide the solution only to the first question as per our Q&A guidelines. Please repost the remaining questions separately.”

Lysine is one of the essential amino acid. It is basic in nature because of the presence of an extra amino group.

pKa is defined as the pH at which different ionization forms of an ionizable functional group within a molecule are present in equal concentrations.

Proteins/Amino acids have a net charge that will predict the behavior of the protein/ amino acid in a particular environment (pH). The net charge on protein depends on two main factors that is-
