摘要

角蛋白是一种天然的生物聚合物，具有良好的生物相容性和生物可降解性。它被广泛应用于生物材料建筑中。角蛋白的二级结构在其应用中至关重要。这种结构与其再生有关。在本研究中，使用二阶导数傅立叶变换红外光谱中的酰胺I、II和III带分析了羊毛再生角蛋白的结构。结果表明，再生羊毛角蛋白通过二硫键的断裂保留了其分子骨架。酰胺I和II带表明，再生角蛋白中α-螺旋与非α-螺旋结构的含量比低于原毛。酰胺III带证实了原毛（35%/31%/22%/13%）和再生角蛋白（26%/35%/23%/15%）的α-螺旋/β-片/β-匝/无规卷曲的含量。

Second-Order Derivation Fourier Transform Infrared Spectral Analysis of Regenerated Wool Keratin Structural Changes

Keratin is a natural biopolymer with excellent biocompatibility and biodegradability properties. It is widely used in biomaterial construction. The secondary structure of keratin is essential in its applications. This structure is associated with its regeneration. In this study, the structure of regenerated keratin from wool was analyzed using the amide I, II, and III bands from second-order derivation Fourier transform infrared spectroscopy. The results showed that the regenerated wool keratin retained its molecular backbone with the cleavage of disulfide bonds. The amide I and II bands indicated that the content ratio of α-helix to non-α-helix structure was less in the regenerated keratin than that of raw wool. The amide III band confirmed the contents of α-helix/β-sheet/β-turn/random coil for raw wool (35%/31%/22%/13%) and regenerated keratin (26%/35%/23%/15%).
