英文品名:D-Glucuronic/D-Galacturonic Assay Kit

规格型号:100 assays (manual) / 1000 assays (microplate) / 1000 assays (auto-analyser)

A simple, reliable and accurate method for the measurement of D-hexuronic acids (specifically D-glucuronic acid and D-galacturonicacid) in plant extracts, culture media/supernatants and other materials.

Suitable for manual, auto-analyser and microplate formats.


D-glucuronic acid and D-galacturonic acid are naturally occurring

hexuronic acids present in glycosaminoglucans, glucuronide conjugates

in mammals and in plant cell wall polysaccharides.

D-Glucuronic acid exists as a component of glycosaminoglucans such

as hyaluronan, heparin and chondroitin sulphate present in mammalian

connective tissue such as cartilage. In the synthesis of glucuronide

conjugates in mammals glucuronic acid is conjugated to xenobiotic

compounds, a biosynthesis reaction known as glucuronidation,

catalysed by the enzyme UDP-glucuronyltransferase and considered a

detoxifying process.

Both D-glucuronic acid and D-galacturonic acid are major components

of plant cell wall polysaccharides. D-glucuronic acid is a component

of arabinoxylan, which consists of a β-(1,4)-linked xylan backbone

substituted with α-(1-2/3)-linked L-arabinofuranose and α-(1-2)-

linked 4-O-methylglucuronic acid. D-Galacturonic acid is the major

component of pectin comprising the α-(1,4)-linked galacturonan

backbone of homogalacturonan and rhamnogalacturonan II, and is

present within the repeating disaccharide unit [,4)-α-D-GalpA-(1,2)-α-

L-Rhap-(1,] of rhamnogalacturonan I.

This kit (K-URONIC) is suitable for the specific measurement of

D-hexuronic acids including D-glucuronic and D-galacturonic acid.
