Immunocytochemical heterogeneity of lactase-phlorizin hydrolase in adult lactase deficiency
Gastroenterology, 1993Adult lactase deficiency may result either from diminished synthesis of precursor lactase-phlorizin hydrolase (phenotype I deficiency) or from altered posttranslational processing of the precursor protein (phenotype II). The aim of this study was to compare the location of lactase-phlorizin hydrolase along the crypt-villus axis in control with adult ...

The Journal of Pediatrics, 1966
The absence of intestinal lactase activity is manifested by lack of absorption of lactose with consequent diarrhea and malnutrition. Two patients with congenital lactase deficiency are described. The association of other disaccharidase deficiencies is documented during the acute stage of the illness.

Calcium absorption from milk in lactase-deficient and lactase-sufficient adults
Digestive Diseases and Sciences, 1986To determine whether lactose influences the absorption of calcium, the uptake of calcium from lactose-hydrolyzed milk and from unhydrolyzed milk was measured in 20 adults: 10 were lactase-deficient and 10 were lactase-sufficient as defined by breath hydrogen test, plasma glucose determination after oral lactose dose, and presence or absence of symptoms

Lactases and their Applications
1981Lactose or milk sugar is a disaccharide found in the milk of mammals. Lactose itself is not sweet, it has a low solubility and it cannot be absorbed directly from the intestine. Lactase splits lactose into glucose and galactose, which have a sweetening power of about 0–8 relative to sucrose; they are 3–4 times more soluble than lactose and are easily ...
