Macromolecules, specifically structural proteins like collagen, are generally the least likely to be broken down quickly due to their complex and stable structures. These proteins provide support and strength to tissues, making them more resistant to enzymatic degradation. Additionally, certain polysaccharides, like cellulose, are also difficult to break down due to their strong glycosidic bonds and the lack of enzymes capable of digesting them in many organisms.
