What is the definition of a complete protein?

Question

Quizplus · Accepted Answer

A complete protein is defined as a dietary protein that contains all 10 essential amino acids. Essential amino acids are those that the body cannot produce on its own and must obtain from food sources. A protein that contains all 20 amino acids would be considered a "whole protein," but not necessarily a complete protein, as it may not have sufficient quantities of all 10 essential amino acids. The functional three-dimensional structure of a protein is unrelated to its completeness as a protein source.
