Pectin - Wikipedia
The principal chemical component of pectin is galacturonic acid (a sugar acid derived from galactose) which was isolated and described by Henri Braconnot in 1825.
Pectin - an overview | ScienceDirect Topics
The chemical structure of pectin contains a significant numbers of connected D-galacturonic acid residues (Fig. 25). The d-galacturonic acid contains four hydroxyl (-OH) and one carboxylic acid (-COOH) groups [299–301] .

2023年11月29日 · 1.2 Chemical Structure of Pectin. Pectin's unique properties stem from its structural characteristics as: DE, molecular weight, and branching patterns. The DE determines the degree of methylation, which in turn affects the gelation and rheological properties of pectin.
1985年12月20日 · Pectin, a polysaccharide, is composed primarily of essentially linear polymers of D-galactopyranosyl uronic acid units joined in α-D≡(1->4) glycosidic linkages; the polymer chains are esterified to various degrees with methanol.
