d-Aspartic acid (d-Asp), an endogenous amino acid present in vertebrates and invertebrates,
plays an important role in the neuroendocrine system, as well as in the development of the …

Using two specific and sensitive fluorometric/HPLC methods and a GC‐MS method, alone
and in combination with D‐aspartate oxidase, we have demonstrated for the first time that N‐…

D-Amino acids administered to animals are absorbed by the intestine and transported through
the blood-stream to solid tissues where they are oxidized in vivo by D-amino acid oxidase …

In this report we present evidence for the presence of free D-aspartic acid (D-Asp) and D-alanine
(D-Ala) in the white and gray matter of normal human brains and brains of individuals …

Background D-aspartic acid is an amino acid present in neuroendocrine tissues of
invertebrates and vertebrates, including rats and humans. Here we investigated the effect of this …

In this study, using an enzymatic HPLC method in combination with d-aspartate oxidase, we
show that N-methyl-d-aspartate (NMDA) is present at nanomolar levels in rat nervous …

D‐Aspartic acid (D‐Asp) is present in invertebrate and vertebrate neuroendocrine tissues’
where it carries out important physiological functions and is implicated in nervous system …

1. D-Amino acid oxidase (D-AAO) oxidizes: D-Met, D-Pro, D-Phe, D-Tyr, D-Ile, D-Leu, D-Ala
and D-Val. D-Ser, D-Arg, D-His, D-norleucine and D-Trp are oxidized at a low rate. D-…

Since their discovery in the mammalian CNS, d-aspartate and d-serine have aroused a
strong interest with regard to their role as putative neuromodulatory molecules. Whereas the …

OBJECTIVE: To determine D-aspartic acid (D-Asp) in human seminal plasma and
spermatozoa in fertile and infertile donors. DESIGN: Prospective observation study. SETTING: …
