Medchemexpress LLC 4-Nitrophenyl α-L-rhamnopyranoside | 18918-31-5 | >99.8% | 285.25 | 25 MG
4-Nitrophenyl α-L-rhamnopyranoside is a commonly used substrate in various biochemical assays to measure the activity of enzymes that hydrolyze rhamnose, such as α-L-rhamnosidase. It has unique chemical properties that allow it to be hydrolyzed by these enzymes to form a yellow product called p-nitrophenol. This makes it a useful tool for detecting and quantifying rhamnohydrolase activity in biological samples or microbial cultures.
- Used as a substrate in biochemical assays to measure α-L-rhamnosidase activity.
- Hydrolyzed to form a yellow product, p-nitrophenol, for detection and quantification.
- Useful for detecting and quantifying rhamnohydrolase activity in biological samples or microbial cultures.
- In vitro, it serves as a rhamnose-α substrate for rhamnosidase.
