Approximately 40% of all known enzymes require helper molecules called cofactors to function correctly. These non-protein chemical compounds are essential for enzyme activity, assisting in the catalysis of biochemical reactions within living organisms. Understanding what are the two main types of cofactors is fundamental to comprehending how enzymes drive metabolism and support life.

According to scientific studies, peptides mediate between 15% and 40% of all protein-protein interactions within human cells, illustrating their fundamental role in biological systems. Understanding what interacts with peptides is essential for comprehending cell signaling, disease mechanisms, and the development of new therapeutics.

The term chelation is derived from the Greek word for 'claw,' a fitting name since these agents grab metal ions tightly with multiple bonds. So, what do chelators do? They are complex molecules that sequester metal ions by forming stable, ring-like structures, a process central to numerous biological, industrial, and medical applications.

Over 20 elements are considered essential for human life, and many of these exist and function as charged ions within the body. These crucial particles are integral to everything from nerve function to bone health, yet others that are chemically similar can pose significant health risks. Differentiating between what are essential and non-essential ions is key to understanding cellular processes and potential toxicity.
