Abstract:

Biologically active peptide (BAP), a kind of peptide molecule having biological activity, is involved in multiple
life activities. BAP plays an important role in human health, and the studies on it have become a hot spot. Meanwhile, a
variety of BAP products with different physiological activities have been developed. In recent years, sea cucumber peptide,
the BAP extracted from sea cucumber, which is a marine echinoderm with high nutritional and medicinal value, has gained
extensive attention. However, most studies on sea cucumber peptide are focused on the extraction process, and its functions
and applications have less been reported. The article is aimed to review the physical and chemical properties, biological
functions and applications of sea cucumber peptide based on the relevant reports at home and abroad, and provide a reference
for further study on human health effects and the relevant mechanisms.

Key words: sea cucumber peptide, biological functions, applications
