Iron(III) citrate - Reference Information
| Introduction | Iron citrate can be regarded as several conjugate bases derived from ferric iron (Fe3) and citric acid. Most of these compounds are orange or reddish brown solids, slightly soluble in hot water, and their aqueous solution is orange or orange in an environment with a pH value of less than 2, and turns green when it is greater than 2. |
| use | iron citrate (III) is a component of the structural basis gated by the outer membrane receptor FecA of E. coli. The binding of ferric citrate initiated a conformational change in the extracellular loop that closed the outer pouch of FecA. ferric citrate, also called ferric citrate, red-brown transparent small flake crystals, or crystalline powder, insoluble in ethanol, slowly dissolves in cold water, and easily dissolves in hot water. Iron citrate is an edible citrate, often used as an additive or sour agent for food and feed. Iron citrate is often used as a food iron fortifier and nutritional supplement in the field of food science; in the field of medicine, it can be used as a radioactive medicine to check abnormal iron metabolism and hematopoietic function; it can also be used as a feed additive. for the pharmaceutical industry and the preparation of lemon ammonium haploid breeding in the preparation of improved nish medium, etc. |
| traits | red-brown transparent flake crystals, or crystalline powder. |
| application | ferric citrate is used in medicine to dialysis blood and regulate iron levels in patients with chronic kidney disease. It acts on the phosphate present in the diet and forms insoluble compounds, thereby reducing its absorption by the digestive system. |
