What is chemical digestion of polymers?

Chemical digestion of polymers refers to the breakdown of complex macromolecules, such as proteins, carbohydrates, and lipids, into their smaller monomer units through enzymatic reactions. This process typically occurs in the digestive system, where specific enzymes target the chemical bonds within these polymers, facilitating their conversion into absorbable molecules like amino acids, simple sugars, and fatty acids. This breakdown is essential for nutrient absorption and energy production in living organisms.
