Protein metabolism refers to the process by which proteins are synthesized, broken down, and modified within the cells of an organism. This area of research focuses on understanding the pathways and mechanisms involved in the metabolism of proteins, including the processes of protein synthesis, folding, degradation, and post-translational modifications. Researchers in this field investigate how proteins are regulated in response to various physiological conditions and how alterations in protein metabolism can contribute to diseases such as cancer, neurodegenerative disorders, and metabolic disorders. Understanding protein metabolism is crucial for developing new therapies and treatments for these conditions.
