Lactose, or milk sugar, is a disaccharide composed of galactose and glucose and has the molecular formula C 12 H 22 O 11. Lactose makes up around 2–8% of milk (by mass). The name comes from lact (gen. lactis ), the Latin word for milk, plus the suffix -ose used to name sugars.
The lactose gives milk its sweet taste and contributes approximately 40% of the calories in whole cow's milk's. Lactose is a disaccharide composite of two simple sugars, glucose and galactose. Bovine milk averages 4.8% anhydrous lactose, which amounts to about 50% of the total solids of skimmed milk.
The ability to digest lactose is not an evolutionary novelty in human populations. Nearly all mammals begin life with the ability to digest lactose. This trait is advantageous during the infant stage, because milk serves as the primary source for nutrition. As weaning occurs, and other foods enter the diet, milk is no longer consumed.
α-Lactalbumin is a protein that regulates the production of lactose in the milk of almost all mammalian species. [8] In primates, α-lactalbumin expression is upregulated in response to the hormone prolactin and increases the production of lactose.
"Life's a climb. But the view is great." There are times when things seemingly go to plan, and there are other moments when nothing works out. During those instances, you might feel lost.
Well, this group historically has domesticated cows and other milk providers and consumed lactose-based, or milk-based products into adulthood, and by natural selection, it’s thought that they’ve developed increased persistence of lactase production by specific gene mutations that are often autosomal dominant.

When L. lactis ssp. lactis is added to milk, the bacterium uses enzymes to produce energy molecules , from lactose. The byproduct of ATP energy production is lactic acid. The lactic acid produced by the bacterium curdles the milk, which then separates to form curds that are used to produce cheese. [11]
