AbstractÂ Â The hydrogen (H2) lactose breath test (BT) is a test commonly used for the diagnosis of hypolactasia. However, its sensitivity is not always good. In the last few years, the new Quick Lactase Test (QLT) has been developed for endoscopic diagnosis of adult-type hypolactasia. The...
- The molecular basis of lactose intolerance. Campbell, Anthony K.; Waud, Jonathan P.; Matthews, Stephanie B. // Science Progress;Sep2009, Vol. 92 Issue 3/4, p241
A staggering 4000 million people cannot digest lactose, the sugar in milk, properly. All mammals, apart from white Northern Europeans and few tribes in Africa and Asia, lose most of their lactase, the enzyme that cleaves lactose into galactose and glucose, after weaning. Lactose intolerance...
- A novel polymorphism associated with lactose tolerance in Africa: multiple causes for lactase persistence? Ingram, Catherine J. E.; Elamin, Mohamed F.; Mulcare, Charlotte A.; Weale, Michael E.; Tarekegn, Ayele; Oljira Raga, Tamiru; Bekele, Endashaw; Elamin, Farouk M.; Thomas, Mark G.; Bradman, Neil; Swallow, Dallas M. // Human Genetics;Jan2007, Vol. 120 Issue 6, p779
Persistence or non-persistence of lactase expression into adult life is a polymorphic trait that has been attributed to a single nucleotide polymorphism ( C-13910T) in an enhancer element 13.9 kb upstream of the lactase gene ( LCT). The -13910*T allele occurs at very high frequency in northern...

Adult-type hypolactasia, also known as lactase non-persistence (lactose intolerance), is a common autosomal recessive condition resulting from the physiological decline in activity of the lactasephlorizin hydrolase (LPH) in intestinal cells after weaning. LPH hydrolyzes lactose into glucose and...

The article presents information related to lactose intolerance, which occurs in people who have deficiency in lactase, an enzyme. It is mentioned that lactase, which is produced in the body, breaks lactose. It is stated that ingredients that contain lactose may be used in lactose-rich foods...
