Abstract
The polypeptide complex of the epiphysis and the peptide AEDG, constructed on the basis of its amino acid analysis, exert similar biological effects. Both bioregulators normalize melatonin synthesis in the pineal gland, functioning of the brain, eye retina, cardiovascular, endocrine, and immune systems; they also act as antioxidants, stress-protectors, and geroprotectors. Within the epiphysis polypeptide complex, free amino acids (3.26%), dipeptides (23.19%), tripeptides (50.72%), tetrapeptides (22.10%), and pentapeptides (0.72%) were revealed by mass spectrometry and HPLC. Peptide AEDG was detected among the tetrapeptides of the epiphysis polypeptide complex by selective reaction monitoring method. The biological effects of the epiphysis polypeptide complex are determined by the effect of its component AEDG.
