How does the body regulate insulin secretion based on absorbed nutrients?

AI Thread Summary
The discussion centers on the process by which the liver regulates insulin secretion in response to absorbed glucose from the small intestine via the hepatic portal vein. It highlights the role of Glut2 transporters in the liver, which facilitate glucose uptake without the need for insulin. The conversation raises questions about how the liver determines the proportions of glucose converted to glycogen, triglycerides, or released into the bloodstream. This regulation is crucial as it impacts blood glucose levels and weight gain. The need for further understanding of these mechanisms is emphasized, particularly regarding their implications for metabolic health.

If all of the absorbed glucose travels from the small intestine via the hepatic portal vein to the liver how does the body know how much insulin to secrete for the liver to convert the glucose to glycogen? Does some absorbed nutrient go via the pancreas?

I'm sorry you are not generating any responses at the moment. Is there any additional information you can share with us? Any new findings?
 
Hi Greg, yes I have made some discoveries recently. The liver has Glut2 transporters which do not need insulin. But I still got a query. The liver will make some of the glucose into glycogen and store it, which is expected. And some is turned into triglycerides. The rest will be put into the blood stream as glucose. I still don't know how it decides what proportions of glucose and triglycerides it will put into the blood stream. Obviously not all of the glucose we eat and is absorbed goes into the blood stream. This can have a bearing on whether the person ends up with high glucose levels or puts on extra weight.
thank kyrani.

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
