Pharmacology
Metabolism/Metabolites
Zinc can enter the body through the lungs, skin, and gastrointestinal tract. Intestinal absorption of zinc is controlled by zinc carrier protein CRIP. Zinc also binds to metallothioneins, which help prevent absorption of excess zinc. Zinc is widely distributed and found in all tissues and tissues fluids, concentrating in the liver, gastrointestinal tract, kidney, skin, lung, brain, heart, and pancreas. In the bloodstream zinc is found bound to carbonic anhydrase in erythrocytes, as well as bound to albumin, _2-macroglobulin, and amino acids in the the plasma. Albumin and amino acid bound zinc can diffuse across tissue membranes. Zinc is excreted in the urine and faeces. (L49)
Absorption, Distribution and Excretion
Upon intravenous injection zinc is distributed to erythrocytes, plasma, and leukocytes; about 80% of the zinc present in the blood is found in the erythrocytes, 12-20% in the plasma, and about 3% in the leukocytes. ... There is a dynamic exchange of zinc between plasma and erythrocytes. Inhalation of dusts of zinc salts results in a transient accumulation in the lung before its absorption into the blood. There is little absorption of zinc or its salts through the skin. ... About 80% of parenterally administered zinc is excreted in the feces, suggesting an enterohepatic circulation for zinc. In humans, about 10% of the absorbed zinc is excreted in the urine, and in tropical climates about 2-3 mg zinc/day may be lost in sweat. /Soluble zinc compounds/
