vProtein: Identifying Optimal Amino Acid Complements from Plant-Based Foods

Figure 1

A simplifed example of complementation with three hypothetical amino acids (vertical axis).

Note that the optimial pairing (B) is balanced in that all of the amino acids contribute to the biological value, while the suboptimal pairings (A,C, and D) are unbalanced in that there are excess amino acids (6, 2, and 1 units respectively) that do not contribute to the biological value.
