Description

General description

Lactose is an important disaccharide in human nutrition, culinary goods, and pharmaceuticals. β-lactose is an isomeric form that is rarely found in nature.

Application

β-Lactose has been used:

• to treat HL-1 cells followed by phorbol dibutyrate (PDB) treatment to study if protein kinase C (PKC) -stimulated accumulation is mediated through galectin-3
• as a component of a media to analyze the extracellular production of protein
• along with recombinant galectin-3 to treat cells for the detection of galectin-3 cell surface binding
• along with recombinant galectin-3 or a control protein to stimulate T cells for apoptosis assay

Biochem/physiol Actions

Beta-Lactose is the beta-pyranose form of the compound lactose.

Lactose, an excipient in a various medication, is used as an additive in a variety of foods. It is utilized as a commercial additive in the food industry due to its texture, flavor, and adhesive characteristics.
