The origins of lactase persistence in Europe. [PDF]
PLoS Computational Biology, 2009 Lactase persistence (LP) is common among people of European ancestry, but with the exception of some African, Middle Eastern and southern Asian groups, is rare or absent elsewhere in the world.

Characterization of putative mannoprotein in Kluyveromyces lactis for lactase production
Synthetic and Systems Biotechnology, 2023 Lactase is a member of the β-galactosidase family of enzymes that can hydrolyze lactose into galactose and glucose. However, extracellular lactase production was still restricted to the process of cell lysis.

A worldwide correlation of lactase persistence phenotype and genotypes [PDF]
BMC Evolutionary Biology, 2010 Background The ability of adult humans to digest the milk sugar lactose - lactase persistence - is a dominant Mendelian trait that has been a subject of extensive genetic, medical and evolutionary research.

Lactase Deficiency and Lactose Intolerance: Current Understanding and Future Directions [PDF]
Journal of Education, Health and SportIntroduction and purpose: Lactose, the primary carbohydrate in milk, requires the enzyme lactase for digestion. Deficiency in lactase activity leads to lactose intolerance, causing gastrointestinal symptoms.

Lactase Insufficiency Revisited
Journal of Pediatric Gastroenterology and Nutrition, 1985 The definition of “insufficient” small bowel lactase activity varies greatly among authors. The present study is aimed at redefining lactase insufficiency by comparing intestinal lactase activity and results of the lactose breath hydrogen test. Primary “insufficient” lactase activity was considered to be present when a child with a normal small bowel ...

Immobilization of enzymes for synergy in polymers to produce lactose free milk [PDF]
Scientific ReportsStabilization of the enzyme lactase is of interest in obtaining lactose-free foods. Optimization of the lactase enzyme activity was investigated using various immobilization methods, including encapsulation, and electrospinning.

Evaluation of Milk and Lactose Sensitivity in Lactase Non-Persistence Genotypes
Proceedings, 2019 Background: Lactase non-persistence, a condition affecting 75% of the world’s population, ischaracterized by inactivity of the lactase enzyme, resulting in lactose intolerance. [...]

LACTASE DEFICIENCY IN CHILDREN
Педиатрическая фармакология, 2011 The topic of the article is the lactase deficiency in children. The most frequent clinical manifestations — diarrhea and flatulence —are not specific to this pathology. Symptoms, typical for the majority of the diseases nosologies of the digestive system,
