Amino Acid Complementarity: A Biochemical Exemplar of Stoichiometry for General and Health Sciences Chemistry  Ed Vitz
Calculations demonstrating amino acid complementarity are presented as an interesting application of stoichiometry. Food proteins are said to have complementary amino acids when the proteins combine to provide amino acids in the proper stoichiometric ratios to synthesize human protein. Implications for vegetarian diet, efficiency of food production, and diet adaptations in various cultures are explored briefly.
