Alkali Scientific p Nitrophenyl β D mannopyranoside, 250 Mg
Nitrophenyl β-D-mannopyranoside is a chemical reagent provided in a 250mg quantity for enzymatic assays and biochemical research. This substrate is commonly used to test the activity of β-mannosidase, an enzyme involved in the breakdown of mannan and other related polysaccharides. The reagent is valuable for studying carbohydrate metabolism, glycoside hydrolases, and enzyme specificity. By using this reagent, researchers can investigate the catalytic activity of β-mannosidase in hydrolyzing β-mannosidic linkages, which plays an important role in plant cell wall degradation, microbial metabolism, and enzymatic reactions in both natural and industrial processes.

Medchemexpress LLC D-Glucose, 4-O-β-D-galactopyranosyl- | 63-42-3 | 98.0% | 1 ML
Lactose is a β-galactoside composed of galactose and glucose residues, serving as the main carbohydrate in mammalian breast milk. This macronutrient acts as an inducer of host innate immune responses, possessing immune modulatory functions. In laboratory settings, it has been shown to inhibit regulatory T-cell-mediated suppression of effector T-cell interferon-γ and IL-17 production. Studies indicate that lactose can also improve acute pancreatitis by modulating early immune cell infiltration and cytokine production.
