Question

Classify each amino acid according to whether its side chain is predominantly protonated or deprotonated at a pH of 7.40. The pKa values of the Asp, His, and Lys side chains are 3.65, 6.00, and 10.53, respectively.

Answer 1

Answer and Explanation:

7.40 becomes lower or shorter than the pKa of functional groups or chains of all the 3 amino acids respectively Lys, His, as well as Asp, although since pH provided throughout the statement. However, all of the covalent chains or bonds of the three compounds or acids (amino) will serve a purpose in the pro-toned pattern.

The pH during which everyone's binding sites will mostly keep track of customer for someone's comparison is:

Lys:

`pH > 10.53`

His:

`pH > 6.00`

Asp:

`pH > 3.65`
