👉 A chelator is a substance that binds to a metal ion, thereby preventing its movement from a cell membrane. This process is crucial in the regulation of cellular processes such as the synthesis and degradation of proteins and lipids. Chelators are used in various applications including drug delivery systems for cancer therapy, and in the treatment of diseases like Alzheimer's and Parkinson's. In simple terms, chelators work by binding to a metal ion that is present within a cell membrane, preventing it from
