ATR-FTIR second derivative spectra of the erythrocytes incubated with different CMNv concentrations (0,80, 320 and 640 μg/mL). (a) Second derivative of skeletal carbons of lipids, primary carbon (2960 cm−1) and secondary carbon (2920 cm−1) bands. b Second derivative of aldehyde bond band (1740 cm−1) related to secondary products of lipid peroxidation. c Second derivative of the amide bonds region, amide I (1660 cm−1) and amide II (1540 cm−1) that are the main bands related to protein structure
