Galactosidases are enzymes (glycoside hydrolases) that catalyze the hydrolysis of galactosides into monosaccharides.. Galactosides can be classified as either alpha or beta. If the galactoside is classified as an alpha-galactoside, the enzyme is called alpha-galactosidase, and is responsible for catalyzing the hydrolysis of substrates that contain α-galactosidic residues, such as ...
β-Galactosidase (EC 3.2.1.23, beta-gal or β-gal; systematic name β-D-galactoside galactohydrolase) is a glycoside hydrolase enzyme that catalyzes hydrolysis of terminal non-reducing β-D-galactose residues in β-D-galactosides. (This enzyme digests many β-Galactosides, not just lactose.
α-Galactosidase ( EC 3.2.1.22, α-GAL, α-GAL A; systematic name α-D-galactoside galactohydrolase) is a glycoside hydrolase enzyme that catalyses the following reaction: [1] Hydrolysis of terminal, non-reducing α- D -galactose residues in α- D -galactosides, including galactose oligosaccharides, galactomannans and galactolipids
Galactosidase alpha is an enzyme that in humans is encoded by the GLA gene. [5] Two recombinant forms of human α-galactosidase are called agalsidase alpha and agalsidase beta (INN). [6] A mold-derived form is the primary ingredient in gas relief supplements. [citation needed]
The hydrolysis of lactose to glucose and galactose is catalyzed by the enzymes lactase and β-galactosidase. The latter is produced by the lac operon in Escherichia coli. [12] In nature, lactose is found primarily in milk and milk products. Consequently, various food products made with dairy-derived ingredients can contain lactose. [13]

Fructose is a natural sugar found in fruits, vegetables, and honey. Fructose can be bad for your health when consumed as part of high-fructose corn syrup in processed foods. Past studies have ...
A galactoside is a glycoside containing galactose.The H of the OH group on carbon-1 of galactose is replaced by an organic moiety. [1]Structure of ONPG, an example of a β-galactoside.
