Effect of hydrogen bonding in collagen
WebAdditionally, the relative area of the peak associated to the peptide bond increased from 5.89% to 6.21% for scaffolds with LMW and to 7.51% for those with HMW chitosan, probably due to hydrogen bonding among polar groups of collagen and chitosan. Furthermore, the relative areas of O 1s and N 1s were assessed. http://www-f1.ijs.si/~rudi/reprints/Eifler-2016.pdf
