:Chlorophenol red §-D-galactopyranoside
Description:
Chlorophenol red β-D-galactopyranoside is a synthetic compound commonly used as a chromogenic substrate in biochemical assays, particularly for the detection of β-galactosidase activity. This compound features a chlorophenol red moiety, which provides a colorimetric change upon hydrolysis, making it useful for monitoring enzymatic reactions. The β-D-galactopyranoside part of the molecule indicates that it is a glycoside, specifically a galactose sugar linked to the chlorophenol red through a glycosidic bond. This structure allows the compound to be cleaved by β-galactosidase, releasing chlorophenol red, which changes color depending on the pH of the solution, typically shifting from yellow to red as the pH increases. The compound is soluble in water and is often employed in microbiological studies, molecular biology, and various laboratory applications to assess enzyme activity. Safety data should be consulted before handling, as with any chemical substance, to ensure proper precautions are taken.
