Decent Essays

Metal Chelation is a process when a polyvalent metal ion form covalent bonds with a drug and binds tightly to form a 5 or 6 membered ring. 5 and 6 membered ring structure are very stable because their bond angle has no ring strain. Thus, when a compound is chelated, it will not be able to pass through the biological membrane, in another words, it will not be metabolise by the body but to be pass through the renal without being absorbed and being excreted though urine.

Insufficient intake of trace minerals can cause symptoms of nutritional deficiency. (Glusker,1999) At certain times, these metal are also use as an active ingredient or excipients in pharmaceutical industry.
