Proteins

Proteins, essential macromolecules found in every living cell, play a fundamental role in the structure, function, and regulation of biological processes. Composed of amino acid chains, proteins serve as the building blocks for tissues, enzymes, hormones, and immune system components. Their intricate three-dimensional structures enable them to carry out diverse functions, from catalyzing chemical reactions to providing structural support. Understanding the properties and functions of proteins is paramount in unraveling the complexities of cellular activities, with implications for fields ranging from medicine to biotechnology.
