Study of the denaturation/aggregation behaviour of whole porcine plasma and its protein fractions during heating under acidic pH by variable-temperature FTIR spectroscopy

Deconvoluted infrared spectra in the amide I′ absorption region upon of plasma solution (6% w/v of protein in D2O) from 30 to 90 °C at pH 4.5 (a) and the corresponding 2D IR synchronous (b) and asynchronous (c) maps.
