"Zinc is absorbed via several gut transporters, e.g. divalent cation transporter 1 (DCT 1). However zinc is also secreted into the gut, partially as a constituent of biliary and GI secretions. This secretion is thought to be important for the homoeostasis of zinc 4. Approximately 70% of the zinc in the circulation is bound to albumin. Storage of zinc in the cells is under investigation, but the protein metallothionein is thought to be important."

"There are five stable isotopes of zinc, yet almost 50% of the naturally occurring zinc is zinc-64. Zinc-66 and zinc-68 account for 28% and 18% of the total respectively. The remaining 4% is mainly zinc-67. Zinc-70 only forms 0.6% of the zinc on earth. Thirty-two isotopes of zinc have been discovered in total 7."
"Zinc concentrations tend to be highest in red meat, liver, milk and cheese."
