Zinc gluconate

Product Description

Name:Zinc gluconate
Molecular Formula:C12H22O14Zn
Molecular Weight:455.68
CAS Registry Number:4468-02-4
EINECS:224-736-9
 It is an ionic compound consisting of two moles of gluconate for each mole of zinc. Zinc gluconate is a popular form for the delivery of zinc as a dietary supplement.
Gluconic acid is found naturally, and is industrially manufactured by the fermentation of glucose, typically by Aspergillus niger, but also by other fungi, e.g. Penicillium, or by bacteria, e.g. Acetobacter, Pseudomonas and Gluconobacter. In its pure form, it is a white to off-white powder. It can also be manufactured by electrolytic oxidation, although this is a more expensive process. The advantages are a lower microbiological profile, and a more complete reaction, yielding a product with a longer shelf life.
Zinc gluconate may interfere with the absorption of antibiotics, so combinations may be unsafe.
