Distribution of free D-amino acids in tissues and body fluids of vertebrates
1Faculty of Pharmaceutical Sciences, University of Tokyo, Japan.
Abstract:
Reports on the distribution, metabolism and origins of free D-amino acids in vertebrate tissues and body fluids are reviewed. The transient emergence of D-aspartic acid during the development of brain and peripheral organs or early stages of life is reported. D-Serine in brain is postulated to be a potentiator for the N-methyl-D-aspartate (NMDA) receptor. Some D-amino acid concentrations in human serum, such as D-Ser and D-Ala, are suggested to correlate with damage to renal function.
