Abstract

D-Alanine (D-Ala) is an unusual endogenous amino acid present in invertebrates and vertebrates. Compared to its L-isomer, the characterization of D-Ala is challenging because of the need for chiral resolution and the low amounts of the D-enantiomer present. With recent improvements in measurement capabilities, research on D-Ala, along with other D-amino acids, has been growing, especially as the functional significance of D-Ala in the mammalian nervous and endocrine systems is becoming known. Here we provide an overview of the distribution, origin, function, and disease implications of D-Ala.
