Val-Ser-His is an example of
tripeptide (containing three amino acids). As we know proteins are bio-polymers made up of small repeating units called amino acids. Amino acids on condensation reaction produces polypeptides. These polypeptides can be hydrolyzed to its corresponding amino acids when reacted with water in the presence of acid. The tripeptide given in problem upon hydrolysis produces three amino acids i.e.
Valine,
Serine and
Histidine (Figure).</span>
Answer:
The correct answer is option C.
Explanation:
Kr is the symbol of a noble gas named krypton.It belongs to the group 18 of the periodic table in which all the elements are less reactive.
These noble gases are highly inert and less reactive due to:
- Completely filled electronic configuration in their valence shell.
- High ionization enthalpies.
- Positive value of electron gain enthalpy.
The answer is C because the nucleus is positive while its surrounded by empty space (gold-foil experiment)
Explanation:
When we add chlorine to a substance or compound then this process is known as chlorination.
For example, a process of chlorination is as follows.
Initiation :
where, Cl* is a free radical.
Propagation:
Termination:
Thus, we can conclude that out of the given options is not formed through a termination reaction in the chlorination of methane.
