The higher degradability of arabinan compared to galactan in the network is due to the architecture in CRP involving more accessible arabinan than galactan. |
The arabinan side-chains were in general more mobile than the galactans, but the long galactan side-chains of potato pectin showed high mobility. |
Contrary to OAAO, acid extraction condition reduce the length of rhamnogalacturonan I side chains by depolymerising arabinan and galactan polymers. |
The function of the arabinan and galactan side-chains of pectin remains unknown. |
