Lactose - Wikipedia

Lactose is a disaccharide.It is a sugar composed of galactose and glucose subunits and has the molecular formula C 12 H 22 O 11.Lactose makes up around 2–8% of milk (by weight). The name comes from lac (gen. lactis), the Latin word for milk, plus the suffix -ose used to name sugars. The compound is a white, water-soluble, non-hygroscopic solid with a mildly sweet taste.
