This compound is normally colorless. However if galactosidase is present, it Hydrolysis hydrolyzes the ONPG molecule into galactose and ortho nitrophenol . The latter compound has a yellow color that can be used to check for enzyme activity by means of a Colorimeter chemistry colorimetric assay at 420 nm wavelength . galactosidase is required for lactose utilization, so the intensity of the color produced can be used as a measure of the enzymatic rate. Though ONPG mimics lactose and is hydrolyzed by galactosidase, it is unable to act as an inducer for the lac operon. Without another lactose analog that can act as an inducer, such as IPTG , galactosidase will not be transcribed and ONPG will not be hydrolyzed.

Unreferenced date April 2008 A galactoside is a glycoside containing galactose . The H of the OH group on carbon 1 of galactose is replaced by an organic moiety. Depending on whether the glycosidic bond lies above or below the plane of the galactose molecule, galactosides are classified as galactosides or galactosides. A galactoside is a type of galactoside in which the glycosidic bond lies above the plane of the galactose residue. The most commonly recognized and used galactoside in biochemistry is lactose . However, other chemicals, such as ONPG , are known, but these are typically synthesized for biochemical assays. An enzyme that breaks the galactoside bond is called a galactosidase .
