laktaz
Laktaz, known in English as lactase, is a disaccharidase enzyme that cleaves lactose, the main carbohydrate in milk, into the monosaccharides glucose and galactose. It is produced by the enterocytes of the small intestine and is located on the brush border of the intestinal lining. In humans, lactase activity is high in infancy and typically declines with age in many populations, a pattern described as lactase non-persistence. The LCT gene encodes the lactase enzyme, with expression regulated by a regulatory region near the MCM6 gene. Variants in this region give rise to lactase persistence, allowing continued activity into adulthood in some populations, notably those with a long history of dairy farming.
Laktaz deficiency leads to lactose intolerance, a condition characterized by digestive symptoms after lactose consumption, such
In industry, laktaz is produced by microorganisms such as Kluyveromyces lactis or Aspergillus oryzae and added
