Definition
Protein functions refer to the diverse roles that proteins play in biological systems, including catalyzing biochemical reactions as enzymes, providing structural support, facilitating communication between cells, and transporting molecules across membranes. These functions are determined by the protein's unique three-dimensional structure, which is shaped by its amino acid sequence.
Summary
Proteins are vital macromolecules that play crucial roles in biological systems. They are composed of amino acids and can function as enzymes, structural components, transporters, and regulators. The specific function of a protein is determined by its unique structure, which is formed through various levels of organization, from primary to quaternary structure. Understanding protein functions is essential for fields such as biochemistry, medicine, and nutrition. Proteins are involved in numerous processes, including metabolism and immune response, and have significant applications in biotechnology and pharmaceuticals. Learning about proteins helps us appreciate their importance in health and disease management.
