That's almost right! You're describing a specific type of synthesis called dehydration synthesis.

Here's a breakdown:

* Synthesis refers to the general process of building larger molecules from smaller ones.

* Dehydration synthesis is a specific type of synthesis where water is removed (dehydrated) from the reacting molecules to form a new bond. This is a common process in biological systems, like the formation of:

* Carbohydrates: Monosaccharides combine to form disaccharides and polysaccharides.

* Proteins: Amino acids link together to form polypeptides.

* Lipids: Glycerol and fatty acids combine to form triglycerides.

Important Note: Not all synthesis reactions involve the removal of water. There are other types of synthesis where water is not a byproduct.
