1-萘-alpha-D-吡喃半乳糖苷

1-Naphthyl a-D-galactopyranoside is a substrate molecule for alpha-galactosidase, which cleaves the glycosidic linkage between the two galactose molecules. This enzyme has been detected in many fungi, including Phanerochaete chrysosporium. It is also found in humans and other mammals. The enzyme has been shown to be inhibited by fluoride and may be affected by pH. 1-Naphthyl a-D-galactopyranoside can be used as a substrate for alpha-galactosidase to measure its activity and kinetic parameters in vitro.
