Figure 3. Average spectra belonging to the left ventricle myocardium, the right ventricle myocardium and the vein of the control and the diabetic groups in the 2800–3030 cm⁻¹ region.

Vector normalization was done in the 2800–3050 cm⁻¹ region. Absorption maxima appear as minima in the second derivatives. (A) Second derivative average spectra belonging to the left ventricle myocardium; (B) second derivative average spectra belonging to the right ventricle myocardium; (C) second derivative average spectra belonging to the vein.
