Question

Quizplus · Accepted Answer

Proteolysis is the process of cutting polypeptide chains of proteins into smaller fragments, typically by enzymes called proteases. This process is important for the regulation of protein function and degradation. Glycation, glycosylation, phosphorylation, and exonuclease digestion are all other processes that modify proteins but do not involve cutting the polypeptide chain.
