| Iodination or chlorination is acceptable but does not kill Cryptosporidium or Cyclospora, and increased contact time is required to kill Giardia in cold or turbid water. |
| Iodination of proteins, glycoproteins and peptides using a solid-phase oxidizing agent, 1,3,4,6-tetrachloro-3a-diphenyl glycoluril. |
| Fortunately, in most countries, lack of dietary iodine has been combated by iodination of common salt. |
| Thyroideal cells are exposed to endogenous H202 that acts as a cofactor for the iodination of thyroxin precursors. |
| Glutathione peroxidase in thyroid tissue also controls thyroglobulin iodination. |
