Protein functions refer to the specific roles that proteins play within living organisms. These functions are diverse and essential for the survival and proper functioning of cells. Proteins are involved in various biological processes, including catalysis, structural support, transport, signaling, and regulation. Catalytic proteins, known as enzymes, facilitate chemical reactions necessary for metabolism and growth. Structural proteins provide the framework for cells and tissues, maintaining their shape and integrity. Transport proteins move molecules across cell membranes, ensuring the proper distribution of nutrients and waste products. Signaling proteins transmit information within and between cells, coordinating responses to environmental changes. Regulatory proteins control gene expression and cellular processes, ensuring that biological functions are appropriately regulated.

Proteins are composed of amino acids, which are linked together in a specific sequence determined by the genetic code. This sequence dictates the protein's three-dimensional structure, which in turn determines its function. The folding of a protein into its functional form is crucial, as misfolding can lead to diseases such as Alzheimer's and Parkinson's. Protein functions can be influenced by various factors, including post-translational modifications, interactions with other molecules, and environmental conditions. Understanding protein functions is fundamental to advancing knowledge in fields such as medicine, biotechnology, and agriculture.
