RESUMO
Functional peptides refer to peptides that are beneficial to life activities or have special physiological activities, also known as bioactive peptides. Oyster is rich in protein and is a good material for developing bioactive peptides, which has great potential as a functional food and great application value in pharmaceutical and medical industry. With the development of modern biotechnology and medical technology, the method innovation of oyster peptide preparation，the absorptivity and biological activity of oyster peptide have been enhanced significantly, which lead to deep recognition of the biological function of oyster peptide and offer the boarder application prospect. The researches on the diversification activities of oyster peptides were summarized in this review, which provided clues and ideas for the development of the oyster peptide applications.
