Overview
Protein metabolism encompasses the integrated anabolic and catabolic processes by which the body synthesizes proteins from amino acids and degrades them back to their constituents. Dietary proteins are hydrolyzed to amino acids and absorbed, entering a dynamic amino-acid pool used for the continuous turnover of structural and functional proteins, enzymes, transport molecules, and peptide hormones. Protein synthesis proceeds through transcription and translation under hormonal and nutritional control, while protein breakdown occurs largely via the ubiquitin-proteasome and autophagy-lysosomal pathways. Surplus or deaminated amino acids are converted to energy substrates or to glucose through gluconeogenesis, with their amino groups disposed of as urea by the liver. Regulation by insulin, glucagon, cortisol, and growth factors couples protein turnover to feeding, fasting, and energy status, and disturbances in nitrogen balance and amino-acid handling accompany metabolic disease, liver dysfunction, and altered body composition. In the context of weight and metabolic management, dietary protein intake and amino-acid metabolism influence satiety, lean-mass preservation, and energy expenditure. Peer-reviewed research in this area addresses the metabolic handling of amino acids, the hormonal regulation of protein turnover, and the role of protein and amino-acid metabolism in liver disease, glucose homeostasis, and body composition, situating protein metabolism within the broader study of nutrition, metabolic regulation, and Obesity Management.
