Lactobionic acid, 4-"O"-β-galactopyranosyl-D-gluconic acid, is a
disaccharideformed from gluconic acidand galactose. The carboxylate anionof lactobionic acid is known as lactobionate.
sugar acid, lactobionic acid can form salts with mineral cations such as calcium, potassium, sodiumand zinc. Calcium lactobionate is a food additiveused as a stabilizer. Potassium lactibionate is added to organ preservation solutions such as Viaspanto provide osmotic support and prevent cell swelling. Mineral salts of lactobionic acid are also used for mineral supplementation.
Lactobionic acid is also used in the cosmetics industry as an antioxidant, [ [http://www.neostrata.com/a_cse/cse_cs_04.asp Lactobionic Acid - a Novel Polyhydroxy Bionic Acid for Skincare] ] and in the pharmaceutical industry as a salt form; for example, the antibiotic
erythromycinis used as the salt erythromycin lactobionatewhen intravenously delivered.
