  2. Lactase - Wikipedia

    en.wikipedia.org/wiki/Lactase

    Lactase (EC 3.2.1.108) is an enzyme produced by many organisms and is essential to the complete digestion of whole milk. It breaks down the sugar lactose into its component parts, galactose and glucose. Lactase is found in the brush border of the small intestine of humans and other mammals.

  3. β-Galactosidase - Wikipedia

    en.wikipedia.org/wiki/Β-Galactosidase

    (This enzyme digests many β-Galactosides, not just lactose. It is sometimes loosely referred to as lactase but that name is generally reserved for mammalian digestive enzymes that breaks down lactose specifically.) β-Galactosides include carbohydrates containing galactose where the glycosidic bond lies above the galactose molecule.

  4. Lactase persistence - Wikipedia

    en.wikipedia.org/wiki/Lactase_persistence

    The lactase enzyme has two active sites which break down lactose. The first is at Glu1273 and the second is at Glu1749, which separately break down lactose into two separate kinds of molecules. [1] At least six mutations (single-nucleotide polymorphisms – SNPs) have been associated with lactase expression. [28]

    On the other hand, the enzyme corresponding to beta-galactosides is called beta-galactosidase; it breaks down the disaccharide lactose for instance, into its monosaccharide components, glucose and galactose. [1] Both varieties of galactosidase are categorized under the EC number 3.2.1.

  8. Lactose - Wikipedia

    en.wikipedia.org/wiki/Lactose

    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.

  9. Galactose - Wikipedia

    en.wikipedia.org/wiki/Galactose

    The hydrolysis of lactose to glucose and galactose is catalyzed by the enzymes lactase and β-galactosidase. The latter is produced by the lac operon in Escherichia coli. [13] In nature, lactose is found primarily in milk and milk products. Consequently, various food products made with dairy-derived ingredients can contain lactose. [14]
