a, the change in analytes on stretching tail tendon fibers of C57BL/6 mice to 4% strain with reduction after removing from testing apparatus (mean ± 95% CI; n = 10 mice). Statistical analysis: two-sided ratio Student's paired t tests. b, the change in analytes on stretching tail tendon fibers of C57BL/6 mice to 4% strain with reduction before removing from testing apparatus (mean ± 95% CI; n = 18 mice). Statistical analysis: two-sided ratio Student's paired t tests. Tendon used was unconditioned. The structures of LNL, HLNL, and DHLNL are shown in Fig. S1. Lys-glycation (the addition of a hexose to the side chain NH₂ of lysine).
