Ca2koordinering
Ca2koordinering refers to the process by which calcium ions (Ca2+) interact with and bind to other molecules or structures. This coordination is fundamental to numerous biological processes and plays a vital role in cellular function. In biological systems, calcium ions are often coordinated by specific amino acid residues within proteins, such as aspartate and glutamate, which have negatively charged side chains. These interactions can alter the protein's conformation, thereby modulating its activity.
One well-known example is the role of calcium in muscle contraction. When a muscle cell is stimulated,
Beyond protein binding, calcium ions can also coordinate with lipids, nucleic acids, and other cellular components.
