Lactobionic acid, 4-"O"-β-galactopyranosyl-D-gluconic acid, is a disaccharide formed from gluconic acid and galactose. The carboxylate anion of lactobionic acid is known as lactobionate.

As a sugar acid, lactobionic acid can form salts with mineral cations such as calcium, potassium, sodium and zinc. Calcium lactobionate is a food additive used as a stabilizer. Potassium lactibionate is added to organ preservation solutions such as Viaspan to 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, [ [ Lactobionic Acid - a Novel Polyhydroxy Bionic Acid for Skincare] ] and in the pharmaceutical industry as a salt form; for example, the antibiotic erythromycin is used as the salt erythromycin lactobionate when intravenously delivered.
