In the formation of a macromolecule, what type of reaction would join 2 subunits together? a) hydrophobic reaction
b) hydrolysis reaction
c) dehydration reaction
d) denaturation reaction

Dehydration Synthesis

Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other via covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.

A covalent bond formed between a carbohydrate molecule and another molecule (in this case, between two monosaccharides) is known as a glycosidic bond. Glycosidic bonds (also called glycosidic linkages) can be of the alpha or the beta type.

Peptide bonds are the key linkages found in proteins. These bonds connect amino acids and provide one of the key foundations for protein structure.

Macromolecules, or polymers, are formed by the combination of smaller molecules or monomers in a specific sequence. This is an energy requiring process called polymerization that produces water as a byproduct.
