Xyloglucan is a hemicellulose that occurs in the primary cell wall of all vascular plants; however, all enzymes responsible for xyloglucan metabolism are found in Charophyceae algae. [1] [2] In many dicotyledonous plants, it is the most abundant hemicellulose in the primary cell wall. [3]

Xyloglucan is a non-ionic, neutral, branched polysaccharide consisting of a cellulose-like backbone that carries xylose and galactosyl-xylose substituents. The configuration of this polysaccharide gives the product a “mucin-like” molecular structure, thus conferring optimal mucoadhesive properties.

Xyloglucan (Fig. 1D), a polysaccharide derived from tamarind seed, forms thermoresponsive gels in water, under certain conditions. Xyloglucan is composed of a (1-4)-β-d-glucan backbone chain (GLU) which presents (1-6)-α-d-xylose branches (XYL) partially substituted by (1-2)-β-d-galactoxylose (GAL). Tamarind seed xyloglucan is composed of ...

Xyloglucan is the quantitatively predominant hemicellulosic polysaccharide in the primary walls of dicots and non-graminaceous monocots and can account for up to 20% of the dry weight of the primary wall. Xyloglucans consist of a β-1,4-linked D-glucose backbone substituted by D-xylose.

2024年5月15日 · Xyloglucan (XG) is the main chain component of the polysaccharide hemicellulose that accounts for the largest proportion in the primary cell wall of dicotyledonous plants . The glucan backbone of XG is composed of β-1,4-D-Glup, and the O-6 position is connected to α-D-Xylp.

2018年2月27日 · Xyloglucan, a natural polysaccharide derived from tamarind seeds, possesses a "mucin-like" molecular structure that confers mucoadhesive properties, allowing xyloglucan formulations to act as a barrier capable of reducing bacterial adherence and invasion and to preserve tight junctions and paracellular flux, as observed in different in vitro ...

The hemicellulose xyloglucan (XyG) is found in the cell walls of all vascular plants and is the major hemicellulose in the primary cell wall of eudicots and nongraminaceous monocots, where it is believed to play an important role in cell wall structure and function.

2022年6月2日 · In this review, we will present what is currently known about xyloglucan biosynthesis in A. thaliana, O. sativa, and S. lycopersicum and discuss the recent advances in the characterization of the glycosyltransferases involved in this complex process and their organization in the Golgi.

Xyloglucan is the quantitatively predominant hemicellulosic polysaccharide in the primary walls of dicots and non-graminaceous monocots. Xyloglucan may account for up to 20% of the dry weight of the primary wall. Xyloglucan has a backbone composed of 1,4-linked β-D-Glcp residues. Up to 75% of thes residues are substituted at O6 with mono-, di ...
