Dehydration means water loss. synthesize means to put together. explain why the chemical process responsible for building a carbohydrate, a fat or a protein is called dehydration synthesis?

Polymerization reactions release water molecules while joining the monomers together.

Explanation:

When simple substances called monomers are joined together to form complex polymers such as proteins and carbohydrates, water molecules are released. For example, the formation of a peptide bond between two amino acids to join them together removes one molecule of water.

Therefore, peptide bond formation during protein synthesis occurs by dehydration synthesis and release water molecules. Likewise, when two or more glucose subunits are joined together by glycosidic linkage, water molecules are released. This is why the synthesis of a carbohydrate, a fat or a protein is called dehydration synthesis.
