Scrambled eggs with green peppers, eggs were heated, protein was deformed, and the spatial arrangement of amino acids changed, which solidified protein.

Heating is one of the physical factors that denature protein.

1, definition: protein was influenced by physical and chemical factors, which changed the spatial conformation of protein and lost its biological activity. This process is called the degradation of protein.

2. The sign of degeneration: the loss of biological function (biological activity) in protein.

3. Consequences of denaturation: The breakage of the secondary bonds and disulfide bonds that maintain the protein space conformation leads to the destruction of the secondary, tertiary and quaternary structures of protein, which does not involve the change of the primary structure and the breakage of peptide bonds; The solubility of denatured proteins tends to decrease, the viscosity increases and the diffusion coefficient decreases; Denatured proteins are easy to digest.

4. Degenerative factors:

Physical factors: heating, violent vibration or stirring, ultraviolet and X-ray irradiation, ultrasonic wave, etc.
