Description

D-Galacturonic Acid is a key uronic acid and a fundamental building block of pectin, a major polysaccharide found in plant cell walls. This high-purity compound is essential for research and industrial processes that require a defined and reliable source of galacturonic acid monomers. It serves as a critical starting material, intermediate, and analytical standard for scientists and manufacturers in the life sciences, food technology, and chemical synthesis sectors.

Application

• Biochemical & Pharmaceutical Research: Used as a substrate or standard in enzymatic studies, particularly for pectinases, polygalacturonases, and other carbohydrate-active enzymes.
• Pectin & Polysaccharide Analysis: Acts as a reference standard in chromatographic (HPLC, GC) and spectroscopic methods for quantifying and characterizing pectin content and structure in plant materials and food products.
• Chemical Synthesis: Serves as a chiral precursor for the synthesis of complex carbohydrates, glycoconjugates, and other bioactive molecules in medicinal chemistry.
• Food Science & Technology: Employed in studies related to pectin gelation, food texture modification, and the development of functional food ingredients.
• Cosmetic & Personal Care: Investigated for potential applications in skincare formulations due to its derivation from natural pectin sources.
• Microbiological Media: Can be utilized as a specific carbon source in selective culture media for microbial studies.
