Bone mineral and matrix components (left column) with their corresponding Raman spectroscopic band (middle column)

Peak allocation	Peaks (cm−1)	Integration interval (cm−1)
v1PO43−	960	918,50–987,15
v1CO32−	1070	1053,44–1105,52
δ(CH2)	1450	1403,80–1491,39
Amide I	1670	1619,22–1709,18
Carboxymethyl-lysine	1150	Individual
Pentosidine	1495	Individual

The right column displays the interval in which the corresponding peak intensity was measured by using OPUS software’s integration function. Carboxymethyl-lysine and pentosidine integration intervals were manually selected for each measurement due to s and interval [3, 32]
