CAS · 59-23-4
Product Overview
D-Galactose丨59-23-4 is a monosaccharide (simple sugar) and an aldose sugar that is an important component of several biological molecules, especially in relation to human metabolism. It is a C6H12O6 sugar, a hexose, and is classified as an epimer of glucose, meaning it differs from glucose by the orientation of a hydroxyl group on one of its carbon atoms (specifically, the fourth carbon). It is widely present in nature, particularly as part of disaccharides like lactose (milk sugar), and plays crucial roles in cellular processes and metabolism.
