Ionic Compounds in Biology

Ionic compounds in biology are substances formed when positively charged ions (cations) and negatively charged ions (anions) bond together through electrostatic attraction. These compounds are essential in many biological processes, such as nerve signaling, muscle contractions, and maintaining cell stability. Examples include sodium chloride (table salt), which helps regulate fluid balance, and calcium compounds important for bones and signaling. Their structure and dissolvability in water allow them to quickly conduct electrical signals and participate in vital biochemical reactions, making them fundamental to life.
