Ferulate polysaccharide esters in grasses enter into free-radical condensation reactions in the cell wall. By radical dimerisation of ferulates, polysaccharide-polysaccharide cross-linking is effected. A range of diferulate isomers are produced, not solely the 5-5'-coupled dimer which has ...
These compounds are widely distributed as conjugates, mainly as esters of quinic acid (chlorogenic acids, CGA). Depending on the identity, number and position of the acyl residues, these acids may be divided into the following groups: mono-esters of caffeic, p-coumaric and ferulic acid; di-,...
The crosslinking of maize cell wall components, particularly mediated by the formation of ferulic acid dimers or diferulates, has been associated with important crop valorization traits such as increased pest resistance, lower forage digestibility, or reduced bioethanol production. However, these relation...
This cross-link- ing role has already been established for non-woody plants (Hatfield et al. 1999), and ferulates of ω-hydroxyacids and diferulates have been identified in suberin depolymeri- zates (Graça 2010). The presence of residual amounts of suberin aliphatics and carbohydrates...
The present invention relates to a synthetic method for the preparation of phytosteryl ferulate using ferulic acid and phytosterols (isolated from soybean oil deodorizer distillate)
DehydrodiferulateSugar beet ( Beta vulgaris L.) seedlings were radiolabelled with 14 C-cinnamate applied to the leaves. Cell-wall phenolic esters were analysed by HPLC. Different phenolic distributions were found in root and shoot, with dehydrodiferulic acids relatively more prominent in the root....
After the extraction of ester-linked ferulates, considerable ultraviolet absorption remained in the hemicellulosic and cellulose fractions, which was increased by the treatment with oxalate or hydrogen peroxide. Therefore, a part of FA esters may form tight linkages within cell wall architecture. These...
These compounds have been related with resistance in a wide range of maize tissues as leaf, kernel, rind, or pith. The role of dehydrodiferulates in the cell wall fortification has been noted in the literature, and this structural resistance could be more difficult to overcome than an ...
