1028 cm-1特征峰结果显示,C−O−C在PRA中伸缩振动,因为羟基赖氨酸的ε-氨基或胶原蛋白的赖氨酸与醛反应形成希夫碱结构,1-金刚烷胺单元的骨架振动峰值为950 cm-1。
The results of the 1028 cm-1 characteristic peak show that C−O−C flex-vibrates in PRA because the ε -amino of hydroxylysine or the lysine of collagen reacts with aldehydes to form a SCHFF base structure. The skeleton vibration peak of the 1-amantadine unit is 950 cm-1.
