Thermodynamic Study of Interaction of Lead(II) with Histidine

lead(II) is used in the manufacture of matches and special explosives such as lead azide, in mordents and pigments for dyeing and printing .More recent applications include use as a heat stabilizer in nylon and polyesters, as a coating for photothermograpic paper, and in rodenticides. It is toxic, and ingestion may lead to acute lead poisoning.. Lead compounds are known to be cumulative poisons, as more than 90% of absorbed lead is fixed in bone tissue from which it is only slowly released over a period of years. Lead (II) has some interesting supramolecular chemistry associated with it because of its coordination to nitrogen and oxygen electron donating compounds.
