Proteins and amino acids also serve as a source of energy, providing about 4 calories per gram.
Aside from these general functions, individual amino acids also have specific functions in many aspects of human physiology and biochemistry. Amino acids serve as precursors for many nitrogenous substances. These include heme, purines, pyrimidines, hormones, and neuro-transmitters, including biologically active peptides. In addition, many proteins contain amino acids that have been modified for a specific function, e.g., calcium binding or collagen cross-linking. Supplemental dietary ornithine can serve as a precursor of arginine. Both ornithine and arginine can support normal wound healing, blood sugar metabolism and proper hormone secretion. Some scientists suggest that supplementation with ornithine may also support proper gastrointestinal functioning.
