Structural characterisation of deer sinew peptides as calcium carriers, their promotion of MC3T3-E1 cell proliferation and their effect on bone deposition in mice

Abstract

Deer sinew peptides bearing calcium promote osteoblast proliferation and improve microstructures in mice with low calcium.

Lactobacillus helveticus-Derived Whey-Calcium Chelate Promotes Calcium Absorption and Bone Health of Rats Fed a Low-Calcium Diet

“…LHWCC had obvious fluctuations at 3410 cm −1 , 2104 cm −1 , 1591 cm −1 , 1422 cm −1 , and 1072 cm −1 . The characteristic peaks of amide A and amide B bands in the sample at 3388 cm −1 are significantly weakened and shifted, which was caused by the inductive effect or the dipole field effect, indicating the binding of calcium ions with N-H [ 24 ]. The absorption peak of LHW at 2170 cm −1 corresponding to the phosphate group O=P-O-H disappeared after chelation, indicating that H in the phosphate group was replaced by calcium ions.…”
