I came across this statement on a web page about protein. "If all the essential amino acids are not present it is not complete ( or usable as ) protein."

I did not believe the part specifically about "usable" to be true according to my understanding. I thought different proteins in the body required different amino acids, but this statement suggests they all require at least some amount of all the essential amino acids.

Could somebody clarify what is accurate?
