Proteins and Amino Acids

Dietary proteins and their constituent amino acids are fundamental to health. This section invites authors to submit original research and review articles in basic or clinical nutrition and regarding mechanisms underlying relationships between proteins (and their constituents, e.g., peptides and amino acids (AA)) in relation to metabolism, physiology and health. We welcome articles in humans and animal models, in health, across the aging life course and during pathological processes where protein/AA constituents affect physiological outcome measures. Relevant in vitro biology approaches are also welcome.

Subject Areas

Potential topics include but are not limited to:
