The condition pyroluria affects the ability to metabolize Vitamin B6 and Zinc. Kryptopyrroles are a byproduct of haemoglobin synthesis. If not properly excreted, the kryptopyrroles bind to receptor sites for B6 and Zinc. One of the metabolites attaches to Zinc and removes it in urine, resulting in zinc deficiency.
My question is does this condition *always* show a clinical marker of low serum zinc levels? Or is it possible to simply block zinc receptors without eliminating zinc from the body, resulting in higher than normal serum zinc levels because of all of the unmetabolized zinc?
