Lactose is a disaccharide sugar synthesized by galactose and glucose subunits and has the molecular formula C12H22O11. Lactose makes up around 2–8% of milk (by mass). 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. It is used in the food industry. WitrynaLactulose is a ketose disaccharide, chemically known as 4-O -β- d -galactopyranosyl- d -fructose. The enzymes used for the biocatalytic production of lactulose are β-galactosidase (EC 3.2.1.23) and β-glycosidase (EC 3.2.1.21) – using lactose and fructose as a substrate. It can also be produced by the alkaline isomerization of lactose. WitrynaIs lactose an aldose or ketose? Lactose is milk sugar — it’s a carbohydrate that occurs in dairy products. Some sugars have structures that are classified as aldoses, meaning they have functional groups called aldehydes as part of their chemical makeup. Lactose isn’t an aldose, but it’s made of two smaller sugars, both of which are aldoses. critical race theory poll questions
