It turned out that some people think that if they do not eat anything, then the level of glucose in the blood will fall and will not be able to rise. Like it's such a cheap replacement for the pancreas. No, citizens, it doesn't work that way.
If we don't eat, our blood glucose levels will indeed go down, but our beloved liver won't let it drop too low. The liver has three ways to do this.
The first way is glycogen.
The liver stores glucose, chemically packed in a tight bag. Roughly like the bricks of the constructor, which the child foolishly connected into one. After that, you can't just separate the part from the piece.
This tight packing of glucose is called glycogen. This is essentially animal starch. You can't dump him alive into the blood. Kissel will work.
To disassemble this glycogen for parts and send individual glucose bricks into the blood, you need a liver. The child calls his mother, and the liver-mother comes and disassembles his constructor into many many separate pieces of glucose. And everyone is happy.
Only this happiness does not last long. About a day.
After a day, the supply of glycogen in the liver ends, and the level of glucose in the blood begins to fall.
Then the liver mama plugs in the fat
This is the second way. Due to the low level of glucose in the blood, our adipose tissue raises the alarm and begins to throw firewood into the liver. I mean, fat.
Fat doesn't just flow into the liver like a viscous yellow river. Not. First, somewhere on the periphery, they break it on the knee like a dry stick, and fragments of fat - fatty acids and glycerin - are already flying into the furnace.
Of all this good, the household mother-liver will bake a lot of glucose and ketone bodies like acetone.
When there is nothing to eat at home, the liver mom will teach our starving tissues and organs to feed on stinking acetone. Well, he will season it with something, persuade him, kiss his forehead, and the hungry internal organs will reluctantly begin to chew this acetone. Fine. You can eat.
Glucose will be there somewhere. Little, but it will be.
Roughly the same method works with proteins.
What kind of trick is this? - The third.
So the liver collects different amino acids in the bottom of the barrel, from which the proteins of our muscles and other useful organs were made. Those, of course, will lose weight, but all the same they will obediently give their last pants to work.
Only one mother-liver knows how to make something useful from any amino acid. Nobody in our body can do this anymore.
Those amino acids that are tastier will be converted by the liver into sweet glucose. And the second grade will be sent to the preparation of acetone soup. Mama's liver is not missing anything.
In short, glucose is never translated in this house. It may not be enough, but it will be.
