Description

Tetragalacturonic Acid is a defined oligosaccharide derived from the partial hydrolysis of pectin, representing a specific chain length of galacturonic acid units. This compound is a crucial intermediate and standard in the research and development of pectin-based products, offering a precise molecular tool for analytical and biochemical studies. It is primarily utilized by researchers and manufacturers in the pharmaceutical, food science, and cosmetic industries for investigating bioactivity, developing functional ingredients, and calibrating analytical methods.

Application

• Analytical Standard and Reference Material: Used for the calibration and validation of HPLC, GPC, and other chromatographic methods in pectin analysis.
• Biochemical Research: Serves as a substrate or inhibitor in enzymatic studies, particularly for pectinases and polygalacturonases.
• Functional Food Development: Investigated for its potential prebiotic activity and as a model compound for designing novel dietary fibers.
• Cosmetic Science: Studied for its skin hydrating and film-forming properties in advanced skincare formulations.
• Pharmaceutical Excipient Research: Explored for its potential use in controlled drug delivery systems due to its gelling and binding characteristics.
• Plant Biology Studies: Used to understand the structure and degradation of pectin in plant cell walls.
