D-Galactose CAS 59-23-4
D-Galactose is a monosaccharide composed of six carbons and one aldehyde, classified as an aldose and a hexose. Both D-galactose and L-galactose occur naturally. D-galactose generally exists in milk as a structural part of lactose. Lactose in milk is broken down by the body into glucose and galactose for absorption and utilization.
