Abstract

The determination of small amounts of D-amino acids in mammalian tissues is still a challenging theme in the separation sciences. In this review, various gas-chromatographic and high-performance liquid chromatographic methods are discussed including highly selective and sensitive column-switching procedures. Based on these methods, the distributions of D-aspartic acid, D-serine, D-alanine, D-leucine and D-proline have been clarified in the mouse brain. As the regulation mechanisms of D-amino acid amounts in mammals, we focused on the D-amino-acid oxidase, which catalyzes the degradation of D-amino acids. Using the mutant mouse strain lacking D-amino-acid oxidase activity, the effects of the enzymatic activity on the amounts and distributions of various D-amino acids have been investigated.
