Mol percentages (mol%) of D-amino acids (D-Asx, D-Glx, D-Ser, D-Ala) and C-normalized concentrations of hydroxyproline (Hyp). Mol% D-amino acids were calculated as the sum of the four measured D-amino acids ((D-Asx, D-Glx, D-Ser, D-Ala) divided by the total sum of THAA without glycine and multiplied by 100.
