Oyster peptide is the application of peptide molecular biotechnology in oyster processing, which is enzymatically hydrolyzed to produce oyster peptide. The small molecule oligopeptides formed by this production method completely retain the original vitamins, trace elements, taurine and other nutrients of oysters, making oysters rich in nucleic acids more quickly absorbed by the body after ingestion than single amino acids or proteins, and more easily absorbed by the body. They have more important biological activities in human metabolism.
