Cellulose
can be assayed using a method described by Updegraff in 1969, where the
fiber is dissolved in acetic and nitric acid to remove lignin,
hemicellulose, and xylosans. The resulting cellulose is allowed to
react with anthrone in sulfuric acid. The resulting coloured compound
is assayed spectrophotometrically at a wavelength of approximately 635
nm.In addition, cellulose is represented by the difference between acid
detergent fiber (ADF) and acid detergent lignin (ADL).Location and
arrangement of cellulose microfibrils in the plant cell wall.
