Abstract

The invention relates to a synthetic oligopeptide containing three aminophenols; cysteine is in the middle of a sequence, one end of the sequence is glutamic acid or glycin, and the other end of the sequence is aminophenol proline or Gamma-propalanine having antiretroviral function. The function of the synthetic oligopeptide is similar to that of glutathione, i.e., removing 1, 1-DPPH free radicals under in-vitro condition, improving the oxidation resistance of anabaena and tobacco cells, and the activity of oxidizing enzymes under salt stress, and improving the heat resistance of wheat seedlings.

Description

technical field

[0001] The invention belongs to the field of agricultural technology. The invention relates to a novel oligopeptide with antioxidant activity synthesized by simulating the structure of glutathione. The invention also relates to the in vitro antioxidant effect of these oligopeptide substances, improving the antioxidant capacity of cells and improving Heat resistance of wheat seedlings. Background technique

[0002] Under normal physiological conditions, the production and removal of reactive oxygen species (ROS) in the body are relatively balanced, but when subjected to various biotic and abiotic stresses, the balance of ROS production and removal in the body is disrupted (Wang Feng etc., Chemical Journal of Chinese Universities, 2007, 28: 1071-1076), resulting in negative oxygen ions (·O 2- ) and hydrogen peroxide (H 2 o 2 ) and other massive accumulation of ROS, triggering oxidative damage to proteins, nucleic acids and lipids.

[0003] Glutathione (GSH)...
