help to calculate this

Hi
I would like to know how many grams of sugar can the body make out of the glycerol in fat.

In each triglycerides there are 1 glycerol, and three fatty acids.

I know that 1 glycerol can become 0.5 glucose.

I would like to know how many grams (averagely, there are different fatty acids obviously) of fat can become, based upon the calculation, on gram of sugar.
obviously, on a molecular level, you need 2 for 1. But I'm talking here in grams.

It is a very tough question though

Convert using the molecular weights of the components

Re: help to calculate this

A couple of points. Protein is not normally automatically partially converted to glucose, but once the process begins, how many grams of protein does it take to make 1 gram of glucose? For instance, if you flood your system with 100 grams of from protein, and 50grams of aminos get converted to glucose, how many grams of glucose does the 50 grams of protein produce? Its not 1:1

Human Fat(TFAs) to carbohydrate direct conversion does not exist in the human body. However, via a pathway involving glycerol, glucose IS created from fat oxidation. I have read that it takes the oxidation of 100 grams of fat to make 18 grams of glucose from 'leftover' glycerol, but, I can not find any hard scientific evidence of this.
