**Function**

Diferulic acids are thought to have a structural function in plant cell walls, where they form cross-links between polysaccharide chains. They have been extracted attached to a few sugar molecules at both ends, but so far no definitive proof of them linking separate polysaccharide chains has been found. In suspension-cultured maize cells, dimerisation of ferulic acid esterified to polysaccharides occurs mostly in the protoplasm, but may occur in the cell walls when peroxide levels increase due to pathogenesis. In suspension-cultured wheat cells, only the 8,5'-diferulic acid is formed intraprotoplasmically with the other dimers being formed in the cell wall.

### Famous quotes containing the word function:

“The uses of travel are occasional, and short; but the best fruit it finds, when it finds it, is conversation; and this is a main *function* of life.”

—Ralph Waldo Emerson (1803–1882)

“For me being a poet is a job rather than an activity. I feel I have a *function* in society, neither more nor less meaningful than any other simple job. I feel it is part of my work to make poetry more accessible to people who have had their rights withdrawn from them.”

—Jeni Couzyn (b. 1942)

“The *function* of muscle is to pull and not to push, except in the case of the genitals and the tongue.”

—Leonardo Da Vinci (1425–1519)
