Activity 3.2 Condensation and Hydrolysis Reactions

CDA3_2.jpg Condensation reactions occur in the synthesis of biological molecules, including proteins, carbohydrates, fats, and nucleic acids. These reactions join smaller molecules into larger molecules. The smaller subunits are called monomers, and the larger molecules formed from them are called polymers. Hydrolysis reactions are the opposite of condensation reactions—they break apart polymers. Digestion of proteins, carbohydrates, fats, and nucleic acids involves hydrolysis of these polymers into their amino acid, monosaccharide, fatty acid, and nucleotide monomers, respectively.
