What is the difference between EDTA and EGTA?

Chemistry is a very important part of the subjects being learned in schools. This subject can be difficult for students actually, but some still have interest in it further their learning in that line. An important and major field of chemistry is medicine. The application of medical knowledge which seems to be a bit difficult is the one that includes the EDTA and EGTA procedures. EDTA stands for ethylenediaminetetraacetic acid, while EGTA means ethylene glycol tetraacetic acid.

Both EDTA and EGTA are chelating agents, and their physical appearance is like a white crystalline powder. EDTA is attracted to divalent magnesium ions, while EGTA is used for divalent calcium ions. Most biologists prefer to use EDTA in studying the behavior of DNA and RNA because it will not affect the activity of the enzyme. The food industry makes use of EDTA as a preservative as it helps to cure mental poison. EDTA agents have more applications than EGTA agents. EDTA has less boiling point, and denser than EGTA.
