Lactose, the primary carbohydrate found in milk, is a disaccharide made of one glucose molecule and one galactose molecule. So, where does glucose come from in milk? The simple sugars needed to build this lactose are primarily derived from glucose taken directly from the bloodstream by the mammary gland.

Over 52% of the total carbohydrate in milk is galactose, produced through the breakdown of lactose. The simple sugar galactose is produced from the digestion of lactose found in foods and through internal synthesis within the body.
