| These bands were attributed to v(C=O) stretching of amides from proteins (amide I, ~1652 cm-1);¦Ä (N¨CH) bending of amides from proteins (amide II, ~1540 cm-1);¦Äas(CH2) and ¦Äas(CH3) bending of methyl from proteins (~1452 cm-1);¦Äs(CH2) and ¦Äs(CH3) bending of methyl and vs (C¨CO) 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 ¨C 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¨C950 cm-1 associated with v(C¨CO¨CC) stretching of polysaccharides. |
