Fat and protein can both be converted into glucose if necessary through a process called gluconeogenesis. The use of proteins or fat for gluconeogenesis requires more energy than the more straightforward metabolism of starches and sugar into glucose.
Identification
Gluconeogenesis occurs when additional glucose is needed by your body, such as after a bout of intense exercise. Glucose obtained from the breakdown of fats and proteins is the only kind of energy that the brain, testes and kidney medulla can use. It is also the only form of energy that your erythrocytes, or red blood cells, can use for their own source of energy.

AND there are more articles concerning protein, I am sure you have taken classes.
But I can still show you that there can be more learning to do.
I would like to end this on a good note.
Stay safe, and God be with you.
