In Vitro Simulated Gastrointestinal Digestion Stability of a Neuroprotective Octapeptide WCPFSRSF and Prediction of Potential Bioactive Peptides in Its Digestive Fragments by Multiple Bioinformatics Tools
WCPFSRSF, an octapeptide (Trp-Cys-Pro-Phe-Ser-Arg-Ser-Phe), has been reported to improve memory in mice, but its gastrointestinal stability is unclear. The objective of this study was to evaluate the gastrointestinal stability of peptide WCPFSRSF and explore the neuroprotective potential of its digestive fragments. Results showed that the content of WCPFSRSF after gastric and gastrointestinal digestion decreased to 71.64% and less than 1%, respectively. Furthermore, the antioxidant and neuroprotective ability of WCPFSRSF were also affected. Eleven and nine peptides were identified in its gastric and gastrointestinal digestive products, respectively. Multiple bioinformatics tools in combination with principal component analysis were employed to assess the physicochemical and structural properties of peptides. Novel peptides generated after gastrointestinal digestion could be classified into three groups: the first group had high bioactivity and bioavailability; the second group had high amphiphilicity, charge, and net hydrogen; and the third group had a long peptide chain. In addition, the representative peptides WCPF and SR showed neuroprotective ability.
