| These bands were attributed to v(C=O) stretching of amides from proteins (amide I, ~1652 cm-1);δ (N–H) bending of amides from proteins (amide II, ~1540 cm-1);δas(CH2) and δas(CH3) bending of methyl from proteins (~1452 cm-1);δs(CH2) and δs(CH3) bending of methyl and vs (C–O) stretching of COO- groups (~1380 cm-1) and Vas (>P=O) stretching, associated with phosphorus compounds (~1245 cm-1). Two bands were of particular importance in reference to the P quota relationship – the band at 1735 cm-1 , associated with v(C=O) of ester groups, primarily from lipids and fatty acids, and the region from 1180–950 cm-1 associated with v(C–O–C) stretching of polysaccharides. |

| 這些譜峰歸屬于蛋白質(zhì)中氨基的C=O伸縮振動(dòng)(氨基I帶,~1652 cm-1)、N-H彎曲振動(dòng)(氨基II帶,~1540 cm-1)、蛋白質(zhì)中甲基的CH2、CH3非對(duì)稱(chēng)彎曲振動(dòng)(~1452 cm-1)及對(duì)稱(chēng)彎曲振動(dòng)、COO-中C-O對(duì)稱(chēng)伸縮振動(dòng)(~1380 cm-1)及>P=O非對(duì)稱(chēng)伸縮振動(dòng)(來(lái)自磷化合物,~1245 cm-1)。其中有兩個(gè)重要的譜峰和P的定量有關(guān)——1735 cm-1處的酯羰基的峰(主要來(lái)自磷脂和脂肪酸)以及1180-950cm-1區(qū)間的峰(主要來(lái)自多糖中的C-O-C伸縮振動(dòng))。 |
