Material properties of concentrated pectin networks

Pectin Methylesterases and Pectin Dynamics in Pollen Tubes

“…It is important to note that the cell wall properties are also affected by the hydrodynamics of the pectin network. The hydration of the network is influenced by the balance between the osmotic stress exerted on the cell wall by the cell contents and crosslinking of the network, which tend to restrict swelling, and the affinity of the network for water, which drives swelling (Zsivanovits et al, 2004).…”

Homogenization of Biomechanical Models for Plant Tissues

“…with p 1 e defined by the two-scale problem (55). Considering the weak formulation of (49) with the test function η = 1 yields…”

“…, and the minimal value of the elasticity tensor is of order 10MPa [55]. Hence the minimal value of the nondimensionalized elasticity tensor E * is approximately 10, and K * p ∼ 0.01 − 0.1.…”

“…It is observed experimentally that the load-bearing calcium-pectin cross-links reduce cell wall expansion; see, e.g., [51]. Hence elastic properties of cell walls and middle lamella depend on the chemical configuration of pectin and density of calcium-pectin cross-links; see, e.g., [55]. This is reflected in the dependence of the elasticity tensor E of the cell wall and middle lamella on the density of calcium-pectin cross-links b e,3 .…”

Wood production, wood technology, and biotechnological impacts

“…2) -potato-pulp shows excellent adhesive properties (Mayer 1998). Up to 17% of the dry matter of the potato tissue is pectin (Mayer & Hillebrandt 1997) which has good water solubility and a high ability of swelling (Jarvis 1984, Ryden et al 2000, Zsivanovits et al 2004.…”
