What is Lactose?
[[File:lactose(lac).png|thumb|Lactose diagram]] '''Lactose''' is a [[disaccharide]] that is made up of [[galactose]] and [[glucose]] molecules. Lactose makes up around 2-8% of the [[solid]]s in [[milk]]. The name comes from the [[Latin]] word for milk, plus the -ose ending used to name [[sugar]]s. Lactose is found in some milk products. == Digestion of lactose == Infant [[mammal]]s are fed on by milk from their mothers. To digest it, an [[enzyme]] called [[lactase]] cleaves the lactose into its two subunits [[glucose]] and [[galactose]] for absorption. == Other websites == * [https://www.nytimes.com/2006/12/10/science/10cnd-evolve.html?
