, Volume: 18( 2)Amino Acid Turnover and Protein Dynamics in Cells
Amino acid turnover and protein dynamics are essential for cellular growth, maintenance, and adaptation. Proteins undergo continuous synthesis and degradation, allowing cells to regulate structure and function efficiently. These processes are tightly controlled to maintain nitrogen balance and cellular integrity. Alterations in protein dynamics are associated with various pathological conditions. Keywords: Protein turnover, Amino acids, Cellular regulation, Nitrogen balance, Biosynthesis
Abstract
Proteins are highly dynamic molecules that perform a wide range of cellular functions, including catalysis, transport, signaling, and structural support. The continuous turnover of proteins allows cells to adapt rapidly to environmental and physiological changes. Amino acids released during protein degradation are reused for new protein synthesis or redirected toward energy-generating pathways under specific conditions. This dynamic balance ensures efficient utilization of cellular resources.Protein dynamics are regulated at multiple levels, including gene expression, translational control, and post-translational modification. Cellular signaling pathways modulate protein synthesis and degradation in response to nutritional status, hormonal cues, and stress conditions. The liver plays a central role in amino acid handling and nitrogen disposal, ensuring that toxic nitrogenous byproducts are safely eliminated.Disruption of amino acid turnover can lead to muscle wasting, impaired immune function, and metabolic imbalance. Conditions such as prolonged fasting, chronic illness, and aging significantly influence protein dynamics. Understanding these processes provides valuable insights into tissue maintenance, disease progression, and therapeutic intervention. Citation: Suresh Nair.

Their precise regulation supports growth and metabolic balance, while disturbances contribute to disease. Continued research in this area is essential for advancing biomedical knowledge and clinical applications. REFERENCES 1. Kuhl H. Pharmacokinetic of oestrogens and progestogens.
