Lactobionate

Lactobionate is a chemical compound that is the calcium salt of lactobionic acid. Lactobionic acid itself is a sugar acid, formed when the aldehyde group of lactose is oxidized. Lactobionate is often encountered in the context of medical treatments, particularly as a component in intravenous fluid solutions.

In medicine, calcium lactobionate is used as a source of calcium. It is often included in solutions administered to patients who have a deficiency in calcium or require supplemental calcium. Its use is favored in certain formulations because lactobionate is a relatively mild anion and is thought to be less irritating than some other calcium salts. It can be found in solutions for parenteral nutrition and in treatments for conditions like hypocalcemia.

Beyond its medical applications, lactobionate can also be found in some food products as a buffering agent or sequestrant. It is a derivative of lactose, a sugar found in milk, which contributes to its biocompatibility and suitability for internal use. The stability and solubility of lactobionate also make it a useful compound in various chemical processes.
