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 …

Peptides and proteins are chiral molecules with their structure determined by the
composition and configuration of the amino acids constituting them. Natural amino acids …

Information accumulated over the past decades on the physiological functions and
metabolic pathways of biosynthesis and degradation of D-amino acids has led to a renewed …

Introduction: Animal venoms are complex chemical arsenals. Most venoms are rich in
bioactive peptides with proven potential as research tools, drug leads and drugs. Areas …

Despite often minute concentrations in vivo, d-amino acid containing peptides (DAACPs) are
crucial to many life processes. Standard proteomics protocols fail to detect them as d/l …

In this study, the aqueous p K a values for 13 neutral, 10 cationic, and 5 anionic carbon
acids, including amino acids, peptides, and related species have been calculated using the …

The skin secretions of Bombina species contain peptides and small proteins with interesting
biological properties. These include bombesin, thyrotropin releasing hormone, BSTI and …

Antimicrobial peptides (AMPs) are evolutionarily old components of innate immunity found in
all living pluricellular organisms. Interestingly, some organisms express families of AMPs …

Life has an unexplained and distinct l-homochirality. Proteins typically incorporate only l-
amino acids into their sequences. In the present study, d-Val and d-γ-hydroxyvaline (d-Hyv; …

For over a century, frogs have been studied across various scientific fields, including
physiology, embryology, neuroscience,(neuro) endocrinology, ecology, genetics …
