Protein is a material located inside food ( Most of the time ).
Some proteins are nuts, meats, fruit, and of course, there are more.
Fact: Some people say Gatorade has protein in it, but it actually doesn't.
There is 0 protein inside a Gatorade.
Just a fact! :)
It is a good thing that put's energy into you and helps you stay awake throughout the day, and keep you going.
But, you cannot eat too much of it, or you could not feel well, as for your body would not cooperate with too much correctly.
Glad I could help, and good luck!
