The distance amongst the molecular chains of PSC was greater than Figure 2a, namely, ASC and PSC showed sharp and intense maximum absorption peaks at ure 2a, namely, ASC and PSC showed sharp and intense maximum absorption peaks at that inside ASC, indicating weaker molecular interactions in PSC. This may possibly be connected to 235 nm and 236 nm, respectively, which can be constant together with the UV absorption characteristics 235 nm and 236 nm, respectively, which can be consistent with the UV absorption characteris the cleavage of the terminal peptide sequence of collagen [29]. The d worth from the second of type I collagen [25]. The aromatic residues, like tyrosine and phenylalanine, have tics of type I collagen [25]. The aromatic residues, such as tyrosine and phenylalanine, somewhat broad peak of ASC was four.18 and that of PSC was four.23 and this reflects the a maximum absorption peak at 280 nm. As shown in Figure 2a, ASC and PSC did not have a maximum absorption peak at 280 nm. As shown in Figure 2a, ASC and PSC did distance among their skeletons [22]. peak at 280 nm. demonstrate a considerable absorption not demonstrate a important absorption peak at 280 nm.two.three.two. FourierTransform Infrared (FTIR) Spectrum FTIR spectra of collagen from lizardfish scales are displayed in Figure 2b. ASC and PSC from lizardfish scales contained 5 significant characteristic absorption bands, including Amide A, Amide B, Amide I, Amide II, and Amide III. The Amide A band (3400440 cm-1) is mostly linked with the stretching vibration of N [18]. However, the hydro gen bond formation results in a transform in wavenumber to a reduce frequency [18]. The Am ide A absorption bands of ASC and PSC had been identified at 3307 cm-1 and 3324 cm-1, respec tively, indicating that N groups have been involved inside the formation of hydrogen bonds, which resulted in a shift in the Amide A band towards the reduced frequency. The Amide B band (a) (b) (3080 cm-1) is linked for the asymmetrical stretch of H2. We showed that the Amide B bands of ASC and PSC have been situated at 3080 cm-1. Within the present study, the positions of Amide I bands of ASC and PSC were discovered at wavenumbers of 1653 cm-1 and 1654 cm-1, respectively; Amide II bands of each ASC and PSC had been situated at 1542 cm-1; and Amide III bands of ASC and PSC were observed at 1240 cm-1 and 1241 cm-1, respectively. Much more over, the ratios of absorption intensities in between the Amide III band and 1450 cm-1 band were approximately 1.0, confirming that the triple helical structures of ASC and PSC have been well maintained [6].
