Interpretive Summary: This chapter briefly introduces basic biochemistry of protein and amino acids (AAs) and their chemical structures, followed by a discussion on the dynamic process of protein and amino digestion, absorption, and turnover in whole body and specific tissues in vivo as the biochemical and physiological basis in assessing protein requirements. The latter part of the chapter provides an in-depth discussion of the latest knowledge of the indicators used to assess protein requirements and AA requirements. The chapter finishes with a discussion of the current recommended intakes for protein and AAs, along with aspects of their use in nutritional assessment and issues in developing recommendations of protein/AAs for health maintenance throughout the life cycle.
