Protein degradation is the process by which proteins in the body are broken down into smaller peptides and amino acids. This occurs through various mechanisms, including the action of enzymes called proteases, which cleave the protein chains. Degradation is essential for maintaining cellular health, recycling amino acids, and regulating protein levels. The body uses protein degradation to remove damaged or misfolded proteins, preventing potential harm to cells. Additionally, it plays a crucial role in cellular signaling and metabolism, allowing the body to adapt to changing conditions and maintain homeostasis.
