Physiological Functions May be related to the functions of plants, such as improving the solubility and water-holding capacity of polysaccharides and playing a lubricating role in water transportation in plants. This polysaccharide has shear thickening properties. The reason may be that the non-methyl esterified glucuronic acid groups on the side chains interact with ions through hydrogen bonding or electrostatic complexation during the shearing process, and the hydrophobic aggregation between the methyl esterified groups on the main chain. However, hydrophobic aggregation is not the main factor for shear thickening.
