Proteinkörper
Proteinkörper refers to the physical form or structure of a protein molecule. Proteins are complex organic compounds made up of amino acids linked together in a specific sequence. This sequence dictates how the protein chain folds into a three-dimensional shape, which is crucial for its function. The proteinkörper encompasses the primary structure (the amino acid sequence), secondary structure (local folding patterns like alpha-helices and beta-sheets), tertiary structure (the overall three-dimensional shape of a single polypeptide chain), and sometimes quaternary structure (the arrangement of multiple polypeptide chains). The precise folding and arrangement of a protein are essential for its biological activity, whether it acts as an enzyme, a structural component, a transporter, or in other roles within a cell or organism. Misfolding of proteins can lead to loss of function or the formation of aggregates, which are implicated in various diseases. Understanding the proteinkörper is fundamental to comprehending protein function and dysfunction.
