Introduction:
Most of the living individuals encompassed with water and organic molecules. These organic molecules are mostly occupied by carbon and hydrogen because these carbon atoms form four covalent bonds with hydrogen atoms. Other compounds that are also essential to life are oxygen, nitrogen, phosphorus, and sulfur.
All living individuals have four types of organic macromolecules, namely proteins,
In living organisms, there are two important reactions, such as hydration and dehydration synthesis. These
