AB  - 1. Oxidative stress in duck embryos undergoes dynamic change during incubation. 
      However, the detailed change characteristics has not been studied yet. Here, we 
      explored the dynamic change characteristics of different antioxidant substances 
      in duck embryo eggs during incubation.2. The following trial assayed antioxidant 
      substances, including vitamins E (VE) and C (VC), glutathione (GSH), reduced 
      glutathione (reduced GSH), oxidative glutathione (GSSG), superoxide dismutase 
      (SOD), catalase (CAT), glutathione peroxidase (GSH-px), and malonic dialdehyde 
      (MDA). Five antioxidant peptides (DY1, DY2, DY3, DY4 and DY5) were screened and 
      their protective effect on HepG2 cells and their mechanism of action 
      determined.3. The results showed that antioxidant substances underwent a dynamic 
      change during incubation through various mechanisms. Moreover, the T-AOC of duck 
      embryos at different incubation times, firstly increased and then decreased, 
      reaching the highest level on d 15 during incubation. The peptide DY2 
      (TVDGPSGKLWRD) exhibited high antioxidant activity in vitro, and is known to 
      regulate the apoptosis pathway in mitochondria.4. The data indicated that duck 
      embryos can be used for the development of related antioxidant products and 
      purification of new bioactive peptides.
