Neurotransmission between neurons, which can occur over the span of a few milliseconds,
relies on the controlled release of small molecule neurotransmitters, many of which are …

d-amino acids, the enantiomeric counterparts of l-amino acids, were long considered to be
non-functional or not even present in living organisms. Nowadays, d-amino acids are …

The ovary is the first organ to age in humans with functional decline evident already in
women in their early 30s. Reproductive aging is characterized by a decrease in oocyte …

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 …

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 …

The hypothesis that l‐glutamate (Glu) is an excitatory amino acid neurotransmitter in the
mammalian central nervous system is now gaining more support after the successful cloning …

Substantial amounts of d-amino acids are present in mammalian tissues; their function,
origin and relationship between pathophysiological processes have been of great interest …

Neurological disorders are major contributors to death and disability worldwide. The
pathology of injuries and disease processes includes a cascade of events that often involve …

Investigations on the occurrence and biochemical roles of free D‐amino acids and D‐amino
acid‐containing peptides and proteins in living systems have increased in frequency and …

Recent evidence has shown that d-amino acids are present in animals and humans in high
concentrations and fulfill specific biological functions. In the central nervous system, two d …
