Related to maltase: acid maltase

α-d-glu·co·si·dase

(glū-kō'si-dās),
Maltase; a glucohydrolase removing terminal nonreducing 1,4-linked α-glucose residues by hydrolysis, yielding α-glucose; a deficiency of the lysosomal enzyme is associated with glycogen storage disease type II. At least five isozymes of maltase exist.
Synonym(s): glucoinvertase

maltase

/mal·tase/ (mawl´tās)
2. any enzyme with similar glycolytic activity, cleaving α-1,4 and sometimes α-1,6 linked glucose residues from nonreducing termini; in humans there are considered to be four such enzymes; two are the heat-stable enzymes, usually called maltases, constituting the glucoamylase complex; the other two are the heat-labile enzymes, usually called sucrase and isomaltase.

maltase

(môl′tās′, -tāz′)
n.
An enzyme that catalyzes the hydrolysis of maltose to glucose.

maltase

An enzyme that splits MALTOSE.

maltase

an enzyme that hydrolyses MALTOSE to glucose. In mammals it is produced in the CRYPT OF LIEBERKUHN in the SMALL INTESINE and is present in the SUCCUS ENTERICUS. Maltase is also present in many seeds.

maltase

an enzyme that hydrolyzes α-glucosides to glucose; there are two maltases found at the brush border of the intestinal epithelium, where they hydrolyze maltose (a product of the digestion of starch) to glucose for absorption. Maltase is absent from the intestine at birth and calves are unable to properly digest starch as a result.

We previously reported that acarbose inhibits maltase glucoamylase, an enzyme in blood that has a-glucosidase activity in the acid pH range and thus interferes with the analysis of GAA (3,12).
The maximum inhibitory effect of the Et0Ac and n-BuOH fractions on maltase activity (at 5 min) was around 35%.
I've been a customer and admirer of Judith Ripka for as long as I can remember," says Shoshanna, "After running into her numerous times around our neighborhood while walking our maltase dogs, we developed a friendship.
1999), a atividade das enzimas amilase e maltase dobra entre a desmama (32 dias) e 42 dias de idade, porem a maturidade digestiva se apresentara muito proxima da condicao adulta apos os 50 a 55 dias de idade.
2013) found that while heat-stress inhibits the activity of sucrase and maltase in the intestinal mucosa of chickens, GABA alleviates this inhibition and this might explain the linear increase in serum glucose by freeze-dried GABA-producer in the present study.
Pompe disease, also known as glycogen storage disease type II or acid maltase deficiency, is a relatively rare lysosomal storage disorder caused by an inherited mutation in the lysosomal enzyme alpha-glucosidase (GAA).
In rats, fed ginger (50 mg% for 8 weeks) enhanced pancreatic lipase activity was found (Platel and Srinivasan, 2000) and also enhanced intestinal lipase, disaccharidases, sucrase and maltase activities (Platel and Srinivasan, 1996).

Then trypsin, lipase, amylase, lactase, sucrase and maltase activities were determined using commercial kits combined with UV-VIS Spectrophotometer (UV1100, MAPADA, Shanghai, China) according to the manufacturer's instructions.
The assay for Pompe disease was made possible by our recognition that acarbose selectively inhibits the interfering enzyme, maltase glucoamylase, present on the surface of granulocytes (2, 6, 7).
