| Research Abstract |
In present study, We quantified the concentration of food-derived peptides and identified the amino acid sequence of the peptides after oral ingestion of collagen peptides. The concentration of food-derived peptides in human blood dependently increased by the concentration of ingested collagen peptides. The food-derived Pro-Hyp decreased and food-derived Hyp-Gly increased in human blood by the long-term ingestion of collagen peptides.
