They include possibly the most significant polysaccharides when considering enzyme use: pentosans (in particular arabinoxylans) and [beta]-glucans, as well as mannans, arabinans, galactans and xyloglucans.

2006) found that arabinan, galactan, and manan were the hemicelluloses most extracted at a low SF of 2.
Among them was the hypothesis of "masked repeating structure" [8] inherent in all the galactans, and extensive elucidation of gelling properties, principles, and mechanisms [9] in hydrated galactan systems.

Pectins are complex carbohydrates with a glucouronic acid/rhamnan main-chains and rhamnan, galactan, and arabinan side-chains.

The chemical data indicated that early strength loss (up to 40%) was associated with loss of arabinan and galactan components.
They proposed a qualitative model in which early strength loss was initially a function of degradation in hemicellulosic side-chain components like arabinan and galactan (Fig.
