A viral protein is both a component and a product of a virus. Viral proteins are grouped according to their functions, and groups of viral proteins include structural proteins, nonstructural proteins, regulatory proteins, and accessory proteins.[1] Viruses are non-living and do not have the means to reproduce on their own, instead depending on their host cell's resources in order to reproduce. Thus, viruses do not code for many of their own viral proteins, and instead use the host cell's machinery to produce the viral proteins they require for replication

example of acid is HCl acid which dissociate in solution to give H+ ion and Cl- ion
Alkaline - <em>a compound that increases hydroxide ions (OH-) when it is dissolved in a solution.</em>
example of alkaline is NaOH which it dissociate in solution to give (OH-) and Na+ ions
PH- <em>value from 0 to 14 that is used to specify how acidic or basic a compound is when it is dissolved in water.</em>
<em> </em>A compound with a Ph below 7 is an acid while a compound with a pH above 7 is alkaline .
PH of 7 is for neutral compounds.
Ion - <em>at atom or molecule that has a positive or negative charge.</em>
