The
interplay of degree of methylesterification (DM), pH, temperature,
and concentration on the macromolecular interactions of pectin in
solution has been explored. Small-angle X-ray scattering complemented
by atomic force microscopy and molecular dynamics was employed to
probe chain dimensions and solution structure. Two length scales have
been observed with the first level of structure characterising chain
clusters with sizes ranging between 100–200 nm. The second
level of structure arises from single biopolymer chains with a radius
of gyration between ∼6 and 42 nm. The development of a range
of macromolecular dimensions in vitro and in silico shows that the
chain flexibility increases with DM and at acidic pH, whereas hydrogen
bonding is the responsible thermodynamic driving force for cluster
formation. High methyl pectins create structures of lower fractal
dimension with less efficient packing. This work unveils pectin conformations
covering most of its industrially and biologically relevant environments,
enabling rational design of advanced biomaterials based on pectin.
