Product Description
Galactose is a naturally occurring monosaccharide (simple sugar) and an essential component of lactose, the primary sugar in milk. Structurally, it is an epimer of glucose, differing in the configuration of a single hydroxyl group. Galactose exists in two forms: D-galactose (the biologically active form) and L-galactose (rare in nature). It is widely distributed in dairy products, legumes, and certain fruits, and plays critical roles in energy metabolism, cellular communication, and glycoprotein synthesis. Commercially, galactose is produced via enzymatic hydrolysis of lactose or synthesized through microbial fermentation.
Key Features
Nutritional & Metabolic Role:
Converted to glucose in the liver for energy production.
Essential for infants as a component of breast milk.
Low Glycemic Index:
Slowly absorbed, making it suitable for controlled-energy diets.
Functional Properties:
Participates in glycosylation processes for cell membrane integrity.
Acts as a precursor for bioactive molecules like glycolipids and glycoproteins.
Solubility & Stability:
Highly soluble in water, stable under neutral pH, but caramelizes at high temperatures.
