How does dehydration sythesis relate to macromolucules and getting energy from food?

Dehydration synthesis deals with the combination of two molecules, or compounds, with the loss of water to form a large molecule (macromolecule). This process uses up energy.

Hydrolysis, the opposite of dehydration synthesis, is a chemical process that degrades another molecules with the aid of water to form a molecule with a different make up. This process gives energy. Organic hydrolysis pairs water with neutral molecules, while inorganic hydrolysis combines water with ionic molecules.

Hydrolysis degrades the raw nutrients in the macromolecules such as protein etc., dehydration synthesis consumes raw nutrients to build up this macromolecules .

Dehydration synthesis is the process involved in making macromolecules

Explanation: Macromolecules are polymers, they have smaller subunits known as monomers that are joined together by bonds to create one single unit, the Macromolecule. The process involved in this creation is the dehydration synthesis reaction in which the monomers are linked with the loss of water. These reactions can be described based on the energy macromolecule formed and from with monomers are involved in the linking. Example, carbohydrates from monosaccharides, proteins from amino acids and fatty acids from acetyl-CoA
