Description

D-Pentamannuronic Acid Pentasodium Salt is a defined oligosaccharide derivative of alginic acid, a naturally occurring polysaccharide. This high-purity, standardized compound is critical for research and development in glycoscience and as a reference standard for analytical methods. It is primarily utilized by biopharmaceutical researchers, diagnostic kit manufacturers, and academic institutions focused on carbohydrate chemistry and marine polymer applications.

Application

• Biomedical Research: Used as a well-defined substrate or inhibitor in enzymatic studies, particularly for alginate lyases and other carbohydrate-active enzymes.
• Diagnostic Reagent Manufacturing: Serves as a critical reference standard or calibrant in the development of diagnostic assays for bacterial infections or inflammatory markers.
• Pharmaceutical Development: Investigated as a potential building block or active pharmaceutical ingredient (API) in novel drug delivery systems and anti-inflammatory therapies.
• Glycoscience & Biochemistry: Essential for studying the structure-activity relationships of alginate-derived oligomers and their biological interactions.
• Analytical Chemistry: Employed as a high-purity standard for HPLC, LC-MS, and NMR analysis to quantify or identify mannuronic acid sequences in complex samples.
• Cosmeceutical Research: Explored for its bioactive properties in advanced skincare formulations targeting skin barrier function and hydration.
