Protein is split into amino acids and then recombined into proteins inside body. The splitting process and recombination process need glucose in blood and, effectively, drain glucose from blood.
In my experience, some of the amino acid sport drinks can drain glucose from blood to the point where I had clear signs of very low glucose levels, including restlessness and shaking limbs.
The glucose level may affect mood and has other interesting effects.
If you look at what carbs, fats and proteins do with you mood, I think you will see that carbs make one relaxed (see relation between carbs and orexin), fats make one jolly (due to endocannabioids) and proteins make one awake (draining carbs from blood, mainly).
