Aspartic acid exists in L-and D-isoforms (L-Asp and D-Asp). Most L-Asp is synthesized by
mitochondrial aspartate aminotransferase from oxaloacetate and glutamate acquired by …

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 …

The current study reported a new keratinolytic bacterium, which was characterized as
Bacillus paramycoides and identified by 16S rRNA, and the sequence was then deposited in …

Cadmium (Cd), by producing oxidative stress and acting as an endocrine disruptor, is known

Abstract d-Aspartate, d-serine and d-alanine are a regular occurrence in mammalian
endocrine tissues, though in amounts varying with the type of gland. The pituitary gland …

The endogenous amino acids serine and aspartate occur at high concentrations in free D-
form in mammalian organs, including the central nervous system and endocrine glands. D …

Cell differentiation during spermatogenesis requires a proper actin dynamic, regulated by
several proteins, including formins. Disheveled-Associated-Activator of Morphogenesis1 …

Simple Summary A deeper knowledge of reproductive biology may be helpful in the donkey

Abstract D-Aspartate (D-Asp) and its methylated form N-methyl-d-aspartate (NMDA) promote
spermatogenesis by stimulating the biosynthesis of sex steroid hormones. d-Asp also …

Simple Summary For proper fertility, the production of good-quality spermatozoa is essential.
Nowadays, many environmental pollutants affect the spermatogenetic process, at different …
