Infrared mapping as figure 2 shows: (a)Lipase, (b) lipase nano silver mesoporous carbon carrier, (c) immobilized lipase. Free lipase infrared mapping of 3411 cm-1 absorption peaks in the expansion for-NH vibration, 2917 cm 1 and 2850 cm-1 place absorption peaks for the expansion of methylene methyl or vibration peak, 2345 cm 1 place absorption peaks for C-H telescopic vibration peak, 1645 cm-1 place absorption peaks is C-O cm-i telescopic vibration peak, 1050 cm-1 place have to absorb the peak is-O-telescopic vibrating peaks. B and c contrast maps of visible, in the immobilized appeared on the carrier in 2917 cm-1 lipase, 2850 cm 1 and 2345 cm-1 characteristics of absorption peaks, show that has been fixed in the carrier in lipase; At the same time, lipase in characteristic absorption peaks doesn't change, so the secondary structure of the enzyme without change. 1050 cm 1 absorption peaks in the immobilized enzyme not reflected on |
