microfibril

 [mi″kro-fi´bril]
an extremely small fibril.

mi·cro·fi·bril

(mī'krō-fī'bril),
A very small fibril having an average diameter of 13 nm; it may be a bundle of still smaller elements, the microfilaments.

microfibril

An extremely thin fibril, or fibre-like strand, which is identifiable only by electron microscopy, and typically composed of glycoproteins and cellulose (for plants) or fibrillin (for animals).

(mī'krō-fī'bril)
A very small fibril having an average diameter of 13 nm; it may be a bundle of still smaller microfilaments.

microfibril

a group of some two thousand cellulose chains massed together in the CELL WALL. Microfibrils are embedded in an organic matrix giving the cell wall great strength.

microfibril

very small fibril within a cell or tissue, made up of bundles of microfilaments

Differential expression of fibrillin-3 adds to microfibril variety in human and avian, but not rodent, connective tissues.
cellulose microfibrils: Cellulose molecules oriented parallel to the long axis of the microfibril in a paracrystalline array, which provides great tensile strength; held in place by the wall matrix and their orientation is closely controlled by the protoplast.
Microfibril angles for both red and sugar maples were found to be 22[degrees] in the juvenile wood and 16[degrees] in the mature wood, corresponding to the transition point of 40 years observed for fiber length and coarseness.
Collectively, relationships between cell expansion and husk leaf development and function could be speculated as follows: assuming that a certain amount of polysaccharides is required for expansion of a cell, during rapid husk leaf expansion before silking, matrix polysaccharides like hemicellulose and cellulose as well as microfibril cellulose increase, causing the husk leaf to expand.
