The band at 912 cm-1 (peak 2) is often attributed to sorption peaks at 1041 cm (peak three) and 1250 cm-1 (peak 4) had been due to presence of C-O C-O stretching and cm (peak vibrations. In addition, 1366 cm-1 (peak 5) stretching [14,15]. The band at Goralatide Epigenetics 912CH2-1rocking2) is Cholesteryl sulfate References usually attributed to C-O stretching and was assigned -1 to CH3 .

FTIR usually do not show acetate [16,17], respectively. FTIR do are matic vibrations and O-H stretching of celluloseany functional groups of AlN which not present within the CA/AlN composites. This are present inside the CA/AlN signal of CA blocks the weak show any functional groups of AlN whichmight be since the strongcomposites. This signals of AlN in the composite. might be because the powerful signal of CA blocks the weak signals of AlN in the composite.Figure 4.
