1205–1219	Aromatic amino acids	Negative	99.5
1220–1260	Amide III, nucleic acid O-P-O	Negative	99.0
1308–1347	CH2 twist and bend (protein, lipid), nucleic acids	Negative	99.5
1376–1398	CH3 deformation	Negative	99.5
1466–1482, 1572–1577	Guanine, adenine	Negative	99.5
1679–1690	Amide I	Negative	99.5

^*The “change” is defined as MR1 plateau minus MR1 exponential cells.

^†The Student's t-test results give the percent of confidence that the means of the spectral regions are different.
