摘要
Edible bird’s nest is rich in protein and have been treasured for centuries for its health benefits such as antioxidant,immunomodulation,and skin-beneficial.The research aimed to validate the in vivo wound healing bioactivity of edible bird’s nest derived peptides(EBNP)as a nutritional supplementation.Structural characterization showed that EBNP had high homogeneity,average amino acid profile,low molecular weight,and compacted three-dimensional conformation of over 80%α-helical structure.Moreover,hydrophobic peptides and single amino acid repeats were found abundantly in EBNP complex,which could be an indication of the skin repairing peptides.As a result of the in vivo validation,EBNP showed higher skin-repairing activity than sialic acid and glutathione,improved the wound healing rate to 86.77%after 8 days of recovery,and resulted in a greater dermis collagen ratio of 30.33%.The research investigated the structural basis,and found dietary peptides as the primary skin-repairing bioactive compounds in EBNP,which enabled EBNP a potential nutritional supplementation for wound-healing.
