Table 5 Hydrogen-deuterium exchange of untreated and hydrothermally (HT) treated Robigus leaves and stems

From: Structure and enzymatic accessibility of leaf and stem from wheat straw before and after hydrothermal pretreatment

Sample Area ratio (AR) Intensity ratio (IR)
  20 h 240 h 20 h 240 h
Untreated leaf 0.59 0.92 1.26 +∞
Untreated stem 0.65 0.90 1.13 0.98
HT-treated leaf 0.58 0.88 1.11 1.06
HT-treated stem 0.62 0.91 0.89 1.07
  1. Data presented as the average of four replicates. AR is the ratio of peak area at OD-stretching (2,800 to 2,159 cm−1) to the total hydroxyl-stretching (2,800 to 2,159 cm−1 and 3,700 to 3,000 cm−1). IR is the ratio of peak intensity at 2,478 cm−1 to 2,362 cm−1.
