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. Depending on whether the glycosidic bond lies "above" or "below" the plane of the galactose molecule, galactosides are classified as α-galactosides or β ...

Galactosidases are enzymes (glycoside hydrolases) that catalyze the hydrolysis of galactosides into monosaccharides. Galactosides can be classified as either alpha or beta.

The most common natural galactoside is milk lactose, and the best characterized enzyme for the cleavage of galactose is β-galactosidase (β-d-galactoside galactohydrolase) of E. coli (Wallenfels and Malhotra, 1961). β-Galactosidase catalyzes the cleavage of β-galactosides to β-d-galactose and the corresponding aglycone, which is glucose ...

β-Galactosidase is an exoglycosidase which hydrolyzes the β- glycosidic bond formed between a galactose and its organic moiety. It may also cleave fucosides and arabinosides but at a much lower rate. It is an essential enzyme in the human body. Deficiencies in the protein can result in galactosialidosis or Morquio B syndrome.

Galectins are β-galactoside-binding proteins and members of a subfamily of the lectin family of carbohydrate-binding proteins. There are 15 known mammalian galectins that participate in a range of biological processes.

β-Galactosidase [3.2.1.23] (Escherichia coli) has a special place in both the history and the practice of molecular biology. It played a central role in Jacob and Monod's 1 development of the operon model for the regulation of gene expression.

a monosaccharide sugar of the aldose group, derived from lactose. d -galactose is found in lactose, in cerebrosides of the brain, in the sugar beet, and in many gums and seaweeds; l -galactose is found in flaxseed mucilage. galactose tolerance test a laboratory test done to determine the liver's ability to convert the sugar galactose into glycogen.

β-Galactosidases are crucial carbohydrate-active enzymes that naturally catalyze the hydrolysis of galactoside bonds in oligo- and disaccharides. These enzymes are commonly used to degrade lactose and produce low-lactose and lactose-free dairy products that are beneficial for lactose-intolerant peop …

A galactoside is defined as a simple sugar compound found in grain legume seeds, consisting of α-d-galactopyranosyl units attached to a sucrose molecule in α-1,6-galactosidic linkages. It is believed to provide energy for the plant embryo during seed germination.

Cyanidin 3-O-galactoside (Cy3Gal) is one of the most widespread anthocyanins that positively impacts the health of animals and humans. Since it is available from a wide range of natural sources, such as fruits (apples and berries in particular), ...
