Determine the net charge of the following tetrapeptide at pH 13.5 that contains the amino acids represented by the single letters "MRPH", such that M is at the amino-terminal end of the peptide and H is at the carboy-terminal end. A. +2 B. +1 C. 0 D. -1 E. -2

The correct answer is E.-2

Explanation:

Net charge or electric charge is the physical property of the matter, which makes it to experience a force, when it is placed in an electromagnetic field. The unit of charge is Coulomb, C.

Types:

Thee are 2 types of electric charges:

1- Positive Charge

2- Negative Charge  

How to calculate net charge?

First we have to look at the composition or our element. Then simply add the number of protons then substrate the total electrons present.
