Chapter 15: The masquerade ball

Intellia

I came back home, I had to study a lot for my exam in medicine university to be able to go to the ball...

So, let’s see glucose metabolism

Now glucose is absorbed through the portal blood to the liver.

Part of it is used in the liver to be oxidized, or used in glycogenesis or lipogenesis.

Another part pass to the systemic circulation to maintain blood glucose level 70-110 mg/dL.

At last, if it is in excess like more than 180 mg/dL ( The renal sugar threshold: RST), it passes to be excreted in urine as a case known as glucosuria…

Glucose is either used intracellularly in oxidation or conversion to biologically active substances

1. Oxidation

A. Major pathways: For Energy production.

1- Glycolysis.

2- Oxidative decarboxylation of Pyruvate.

3- Citric Acid Cycle "C.A.C".

B. Minor pathways: Not for Energy production.

1- Hexose Monophosphate Shunt "HMS".

2- Uronic Acid pathway

2. Conversion to biologically active substances
