The researchers used genetic manipulation to enable the experimental mice to metabolize glucose and fatty acids, but not acetic acid, and then compared the physical conditions of these experimental rats and normal experimental rats when they were fed bait and fasted for 48 hours  In the state of being forced to go on a hunger strike for a long time, the body temperature and endurance of the experimental mice that cannot metabolize acetic acid are significantly reduced
Acetic acid is the basic substance in life, and the body structure of the experimental mice is very close to the human body
Adenosine triphosphate produced by metabolism is the source of energy for life activities.
